I know I've made many mistakes in my life and that I deserve oblivion here in the Ein Sof but please, send me back! I... I won't let them suffer this war by themselves! I won't let her fight this war by herself!
~ Cassiel

Summary

Cassiel is an Angel that was employed by Heaven to go and assist Eden Squad in their attempt to stop Lilith from breaking open all Seven Seals and triggering Armageddon. Initially, she followed her orders to the letter however, she became attached to her charges and began to question her superiors. Cassiel eventually rebelled against Zadkiel and Heaven, resulting in retribution. She was seemingly killed by the Seraph Anael however, it was revealed that Anael faked Cassiel's murder on the request that she guard Eden Squad from the hands and schemes of Zadkiel.

History

Born into Zadkiel's Heaven to two unnamed Angels, Cassiel was just another nameless face that resided within the multitude of the winged celestials that resided in Shamayem. Raised in the lower end of the economic scale within the First Heaven, Cassiel strived to be great. Strived to break free from her life down in the slums of Heaven. Throwing herself into her studies and going to one of the many education centers within the First Heaven, Cassiel's talent was noticed by one of her teachers who called her parents for a conference of which the higher schools within the Fifth Heaven was recommended for Cassiel. While they were worried about the cost of such an education, Cassiel and her family was informed that the costs would be covered by the school.

For the next seven years, Cassiel learned under the brightest minds in all of Heaven, shooting to the top of her class. While other angels enjoyed their lives in the Fifth Heaven and experienced their youth, Cassiel spent her time within the Academy's libraries, learning all she can. Her grade-skipping also earned her the animosity of some of the higher level angel children, who stated that a filthy malakim is not allowed to sully the purity of the fifth Heaven. Subjected to emotional torment and forced isolation, Cassiel only made one friend the entire time she was there. An angel by the name of Lailah who was born as the younger sister of one of the Ten Great Seraphim.

Their friendship became Cassiel's sole light in the Fifth Heaven as more and more higher-level angels began to despise her for the fact that she was there. At the end of her time in the Academy, Cassiel was called by the Seraph Raguel to his office to discuss her future in Heaven. Stating that she wanted to serve, Raguel recommended for her to join Heaven's Army. She accepted. With the good news of a secure future, Cassiel informed Lailah of her decision. Lailah frowned at her decision and informed Cassiel that she's serving a world ruled by deceit. Cassiel rebuffed her, stating that Zadkiel had brought prosperity to Heaven to which Lailah shook her head in disapproval. Lailah informed her that she was joining the Grigori Organization on Earth much to Cassiel's dismay. The rest of their final semester saw the two slowly growing apart until the day they graduated. Cassiel left the Fifth Heaven for the Fourth Heaven without saying a word to her friend.

Cassiel's training within Zebul was more or less harsh. Joining Heaven's Combat Academy, Cassiel trained there alongside all of the other soldier prospects. She quickly found herself in a place that she was unfamiliar with as physical skill was just as valued as her academic skill. For the first several months, Cassiel was beaten over and over again in every sparring match and came in last within exercises. Overall, outside of Academics, Cassiel was the worst-ranked student within the Academy. However, her determination would not allow her to remain at the bottom. Spending her nights training, she was caught by her fellow angel, Dumah. Dumah and Cassiel couldn't be more opposite from each other. Despite the both of them being Malakim, Dumah excelled in both physical exercises and academic work. As such Cassiel saw him as a rival of sorts despite the two never interacting with each other. He pointed out what was wrong with her form. Their rendevous continued over Cassiel's first year in the academy to the point where it was routine. Slowly but surely, Cassiel rose from the bottom ranks and ascended.

Dumah and Cassiel eventually became the two front runners in their class. The two remained friendly with their competitions and over time, Cassiel began to feel something. At the end of their time within the Combat Academy, Cassiel and Dumah were split apart, much to her grief. But to her surprise, Dumah continued to correspond with her. As Cassiel toiled within the lower levels of Heaven, being more as a cop rather than an actual warrior, Cassiel soon realized that she was back at square one.

As the centuries flew by, Cassiel witnessed it all from Heaven's News Outlets. She watched the rise of Islam and Christianity, showing possible signs that God and the Archangels still worked. But they were all just rumors after all. Cassiel knew they were. But despite that, she held a small amount of doubt within her that these rumors were more than just rumors.

Soon, news of a traitor began to circulate around Heaven which reunited Cassiel with Dumah. Their flights were sent to Earth due to the news that one of their own had consorted with another pantheon. Upon arriving and careful investigation, Cassiel was shocked to run into Lailah, her former best friend. The Seraph looked at her with a measure of pity. Hoping that she knew who the traitor was, Cassiel asked her. Lailah revealed herself as the traitor but asked Cassiel what crime she had committed. Cassiel retorted by stating that her crime was against Heaven itself and that she consorted with False Gods. She was infuriated when Lailah's pity for her kept growing. Her eyes. Her eyes mocked her. Cassiel called for backup but was quickly and effortlessly subdued by Lailah. She stated that there was a gap between them that she could never breach with her current mindset. She called Cassiel a mindless dog and a pawn in her brother's game. She knocked her out before leaving.

Following the failed mission, Cassiel was plagued by Lailah's words. She watched as the Great Seraph Zadkiel publically denounce his sister over the Heaven's Public Astra. Her parents praised her for attempting to subdue a traitor and she was recognized publically. Eventually, Cassiel decided to retire but was stopped by a visit from one of the Great Seraphs, Raguel. Raguel stated that he needed a bodyguard. As she was about to refuse, Raguel offered her a substantial amount of money to help get her parents out of the slums of the First Heaven. Accepting, Cassiel found herself working for Raguel. However, the Angel of Law did more than make her a bodyguard. Cassiel became his understudy, his student for all intents and purposes. She realized that her bodyguard position was nothing more than a cover for the public as she learned underneath him.

Overtime, Raguel revealed to her that her tutelage was all preparation for what was to come in the future. Confused, Cassiel could do nothing but nod. It was the moment that Cassiel was reassigned at the request of Raguel that she felt that she had somewhat understood. Cassiel was once again sent down to Earth to guard one Adrian Mariner after his soul was freed from Hell by his friends. A job that would finally reveal to Cassiel the true nature of the Heaven she dearly loved.

Appearance

Cassiel is the average celestial being that resides within the Abrahamic Heavens. She was born a Malakim and ascended through the ranks as her power increased and was promoted. Cassiel has light violet eyes that shine like an amethyst whenever her eyes glow. Her hair is long and wavy, reaching down to her mid-back. Gremory comments that her hair has the same texture and feeling as silk. The silky feeling of her hair is something that Cassiel states that is completely natural and not the product of hair care use.

Cassiel has a tall and lean figure that's easy on the eyes of men. Her figure is similar to that of a swimmer training for the Olympics. She stands at a height of 5'10 standing. She is taller than the average human female. She doesn't mind her appearance as being average compared to other angels.

Like all other angels, Cassiel possesses a pair of dark violet wings. Her wingspan is about 5 meters in total length. The tips of her primary, secondary, and tertiary feathers fade into a lighter shade of violet. Originally, she possessed only a single pair of wings but as she ascended the ranks of Heaven, she gained more. When she reached the rank of Cherubim, Cassiel gained four more pairs of wings, totaling in ten wings. After she became a Seraph, Cassiel gained a final pair of wings numbering in a total of six pairs of wings. Her halo has changed over the years as well. As a Malakim, her halo was a basic circular violet halo which was the same color as her wings. After she ascended to the rank of Cherub, Cassiel's halo became a concentric flaming violet wheel. After she became a seraph, she gained a small cross in the middle of the halo.

Cassiel's wardrobe is limited and she does not indulge in shopping for clothing due to her upbringing. Her wardrobe possesses a grand total of seven different shirts, three long coats, and four pairs of boots. Her most frequented use of clothing is a white button-up shirt and a black long coat. She wears maroon pants with black business shoes.

While she was a Cherub, Cassiel can project an aura that alters her appearance drastically. In this altered appearance, Cassiel becomes a flaming figure surrounded by eight revolving concentric rings that radiate a soft violet light. The wheels possess eyes upon eyes. As a Seraph, Cassiel's form becomes highly volatile and destructive to the point where she has to actively suppress her power in order to keep it from destroying everything around her.

Personality

Cassiel is oftentimes a naive, gullible, compulsive, strong, and determined Angel. Like most angels within Shamayim's Forces, Cassiel is extremely composed, expressing very little emotion. Years of training have taught her that emotions often times get in the way of missions. Despite this, Cassiel does not display the mocking apathy or blatant racial superiority of her fellow angels such as Zadkiel. Her delayed reaction and lack of understanding of social norms lead her to misunderstand sarcasm most of the time and has occasionally gotten her in trouble within the Human World.

Like all other Angels, Cassiel displays faith in God, the creator of her race. However, it isn't like the blind zealotry that the other Angels have been brainwashed into having. Several disciplinary records of her from her time under Camael's command has stated that she has questioned God's intentions at more than one point in her service. This has led other Angels to often ostracize her for not displaying the same blind faith in God as they have despite her loyalty to him. Raguel has stated that she has broken away from the hive mind that the Seraphim have instilled in the entirety of Heaven's populace. Her faith in God has been shaken at more than one point such as when Asherah revealed that God willingly abandoned Heaven. This partially contributed to her downward spiral and her willingness to utilize the forbidden power of the Heart of Purgatory in order to replace God as ruler of Heaven.

After spending years on Earth, Cassiel has loosened up, so to speak. It has been stated by Lailah that spending time around Eden Squad has caused her to revert to her self prior to her enlistment within Heaven's Army... somewhat. Cassiel would never be the troublemaker she used to be in school, however, she has been known to bend the rules from time to time. She also picked up what she refers to as a "few dirty tricks". She is willing to trick or distract people in order to escape from situations. An example is when Gremory had her trapped inside a Divine Sigil. She managed to distract Gremory long enough to use what psionic powers she had unsuppressed in order to break free. She also picked up a few tricks from the demons such as Gremory and Crowley which she used in Heaven's Civil War such as performing subterfuge against the Loyalist Faction.

During the Second Civil War, Cassiel underwent a massive shift in her personality. She became cold, calculated, and manipulative. She actively used Eden Squad for her own personal gain such as taking out Camael's forces which she labeled as "working with Demons" and "wanting to restart the Apocalypse". She did everything she could to win the War and access the Heart of Purgatory after she learned of it from the old texts hidden deep within the archives of Hekhalot within the level of Araboth.

While she was connected to and hosting the Heart, Cassiel became prideful and arrogant. The power she used twisting her mind to the point where she labeled herself as the New God of all Creation. She became even colder, colder than she was while she was at war with Camael. She killed Camael and all her forces without a second thought, annihilating them entirely. Cassiel even went so far as to make examples of Camael and his forces, displaying their corpses live on Heaven's Astra as well as broadcasting herself to the other pantheons. She outright stated that she would crush any pantheon that would get in the way of Heaven.

Upon being released from the influence of the Heart, Cassiel was instantly hit with the weight of every action she had committed. Hated by her fellow Angels, Cassiel did not dare go back to her home and instead hid on Earth. She felt guilty of her actions during the War to the point where she allowed two angels to nearly have their way with her only to be saved by Adrian and Ruby. She pledged herself to him as recompense of how she treated them prior to her disappearance. Even though Adrian has stated that she doesn't need to go that far, she still continued to protect him and throw herself in front of danger to protect him, causing Adrian to worry for her.

Her love life is complicated. She is bisexual, having once been in love with her fellow soldier, Dumah, and is currently in a complicated relationship with one of the Pillar Demons, Gremory. Her actions throughout the years have put her at odds with Gremory, who she often fought with multiple times. Despite people saying that their relationship was doomed to fail, Cassiel still holds out hope that they can make it and have something beautiful come out of their relationship. She is an idealist when it comes to love, often hoping for the best despite the bumps she meets along the road in her relationships.

Each ascension within each level is infinitely greater than the last.

Standard Equipment:

  • Staff of Moses
  • Cassiel's Twin Short Swords
  • Magically Enhanced Heckler & Koch USP with .40 S&W Cartridge containing Iron laced Bullets as well as Sigil Bullets
  • Angelic Akashic Tablet (Briefly)

Intelligence: Extraordinary Genius. Cassiel is one of the most intelligent angels that signed up for Heaven's armies when she was younger, scoring higher than any of the possible candidates. Well versed in several fields of magic and later science and mathematics, Cassiel used her genius to her advantage on the field and possessed immense leadership skills. According to Zadkiel, Cassiel was ranked the first in her leadership classes and was the first female angel to do so in over 500 years during that time. Her understanding of mathematics is intense and was particularly versed in calculus, Euclidean geometry, as well as tensors. She is also well versed in the fields of science, taking particular interest in chemistry and going so far as to major in it during her time spent in the human world. Before she was sent to serve in Heaven's Armies as a Malakim, she learned much under Raguel, one of the Ten Great Seraphs, who took her under his wing and has a well-versed understanding of Heaven's Laws and Systems as well as an understanding of interpantheon politics.

Weaknesses: Sometimes lacks an understanding of social norms. Due to her time spent studying, Cassiel is somewhat of a NEET and an introvert, rarely interacting with others. Natalia mentions that she has stunted social growth. Utilizing the Staff of Moses requires massive amounts of energy which can lead her extremely fatigued. The Lumen of Sovereignty's Alter World requires her to remain still while she synchronizes with the environment of the Third Heaven which can lead to others attacking her. Also exhibits the weaknesses of Angels such as Divine Sigils, Divine Weaponry, and Holy Fire | While connected to the Heart, her body began to break down due to the stress of housing such immense power

Notable Attacks/Techniques:

Magic: Magic refers to the ability to affect the world and change it via supernatural means. It is a force that pervades throughout the entirety of the worlds as well as the higher worlds but to a lesser degree. All beings are capable of casting magic through sufficient research and practice. As an Angel, Cassiel particularly excels Enochian Magic, the magic of the Angels.

  • Enochian Warding: Enochian Wards are specialized wards designed to mask the presence of beings from Angels and Demons, repel Angels and Demons, and perform exorcisms. Enochian Magic can also be described and stored into sigils.
    • Exorcisms: Exorcisms are a magical art that banishes Demons, Angels, Ghosts, and Gods. Higher-level beings may require multiple high-level beings performing exorcisms at the same time. Exorcisms can also be used in the form of sigils that can be triggered.
    • Emperyan Masking: Emperyan Masking is a spell used by angels to hide from other angels. It was initially developed to slash the name of any rebellious angel from the records of Heaven and make it so that their family would no longer be able to find them. However, despite initial intentions, the spell was later deemed illegal by the Empyrean Council due to its capability in assassinations.
    • Be Gone: An Enochian Sigil Spell similar to Abolishment Spells. Be Gone is a multi-purpose spell that is designed to banish Gods, Angels, and Demons depending on what Rune is used.

Master Hand-to-Hand Combatant: From the very beginning, Cassiel was a highly accomplished fighter and was deemed amongst the best of Heaven's soldiers. Her skills are great enough to fight stronger opponents. She is capable of fighting Gremory, despite the vast difference in power between them, being able to land extremely vicious blows on before she was defeated due to Gremory's superior strength and skill. When her Grace was stolen by the Seraph Metatron, Cassiel was rendered mortal but proved to be skilled enough to defeat and kill several angels that she ran into. Her mortality, which she believed to be a hindrance, did not hamper her ability to fight. As a full-blooded Angel, she is physically superior to Adrian and Natalia, who are Nephilim, and was able to restrain the former when he was being overtaken by the influence of the First Curse. She was also able to briefly hold her ground against the Knight of Hell, Apollyon, when he planned on overtaking all of Hell and bring death to Creation itself.

Master Swordswoman: Far more skilled than Adrian and Ruby during their first meeting, Cassiel wields two twin swords which she uses to fight. She has mastered three forms of Heavenly Sword Combat known as First Flight, Second Flight, and Fifth Flight. She can use these forms to deadly efficiency to effortlessly disarm her foes, overpower them, and bypass their defenses with precise strikes and blows. She was briefly able to stand against Anael but ultimately lost due to the Seraph's power and skill.

  • First Flight: First Flight is a sword style which serves as the basis for the other forms of armed melee combat used by the other angels. It is basic and rudimentary but it can be extremely potent in the hands of a master. In practice, the First Flight consisted of basic strikes and broad parries. It favored direct and powerful strikes over the unpredictable movements such as Final Flight or the acrobatic mobility of Zenith. However, this is extremely misleading. First Flight will always involve highly aggressive attacks and immediately return to a defensive position.
  • Second Flight: Second Flight, also known as Swan Wings, is an elegant and highly defensive form of bladed combat. It emphasizes parries and counter-attacks, building an absolute defense. In a sense, Second Flight is the most defensive form of armed combat within Heaven. However, there is a glaring flaw. Second Flight can only be used with swords and daggers. It is highly incompatible with spears and hammers.
  • Fifth Flight:' Fifth Flight, also known as Reisha, is a balanced form of armed combat that emphasizes counter-attacking and offensive moves. Reisha is a physically demanding style that calls for the user to be able to rapidly shift from a defensive form to an all-out attack. Reisha Users can attack when their foes least expect it. Strength and Speed were demanded from the user to be able to follow up a block or parry after initiating a powerful series of strikes.

Proficient Torturer: Cassiel is highly proficient in the art of torture. She can torture demons and other beings into giving her information on what she wants in a matter of minutes.

Malakim Physiology: The standard run of the mill angel. Malakim are the lowest level of angel in terms of triadic ranking. Akin to that of a citizen within a country, Malakim have little to no political influence despite voting and protesting. Malakim also have the lowest level of power, though power levels among Malakim vary. Malakim possess a halo and a single pair of wings that can be used for flight. Like other Angel Classes, Malakim possess highly volatile forms which are capable of slashing and incinerating the corneas of humans and monsters.

  • Grace: The "soul" of an angel. It is essentially their life essence but not at the same time. An Angel is their grace and has been described by Belpehgor while torturing an angel to be a "multi-dimensional wavelength of pure celestial energy". It endows them with their abilities as well as their immortality. Removal of their grace renders an Angel mortal, ripping them of their wings and halo and turning them into slightly stronger humans.
  • Vessel: In the event that she needs to hide and or recover, Cassiel can possess humans and inhabit their bodies. Angels require the permission of humans to enter their bodies, otherwise, they can't. It is also noted that an angel needs to continue having a human's permission in order to remain within that body. While inside the body, the vessel gains all the abilities of the Angel. However, if Cassiel so desires, she can lock away or destroy the soul inside the body and occupy it. Angels can possess dead bodies or vegetative humans as it is essentially empty.

Cherubim Physiology: The second highest rank of Angel that exists within the Third Triad of the Angelic Hierarchy.

Cherubim have been known to turn people into worthless sacks of flesh or spirit.

Seraph Physiology: Ascending to the highest class of Angel in existence, Cassiel is one of the most powerful beings in Heaven and in Creation with her power being able to rival the Chief Gods in combat. Like other Seraphs, she possesses six pairs of wings and a massive halo behind her head that glows brightly in the sun. As a Seraph, Cassiel possesses an extremely destructive form that she has to keep sealed away for fear of incinerating everything around her just by being there. Humans and other beings with the exception of powerful monsters, Prophets, powerful humans, and Gods are capable of perceiving her form without any adverse effects to them.

  • Destructive Countenance: Her true form is extremely destructive, burning everything around her to ashes.

Authority of Boundaries: A former power belonging to Raguel before he begged God to save Cassiel by offering up his own Grace. Cassiel has the power to manipulate the concept of Order and Laws. She can force her will into the world to affect the laws that comprise it. She can change laws for a fixed amount of time with her initial limit being ten seconds.

In addition, Existence Denied has varying levels of success and depends on the strength of the being she uses on.
