Excalibur (Monarchverse)

Summary
Excalibur is one of the 13 Great Dreams of Humanity. It is a weapon that never existed in human history, and was instead formed from the dreams and legends of the weapon. It is only created once, when Alex briefly combines his Affinity with Markus's, allowing Markus to form it using Chrysaor's sword as a base, allowing Chyrsaor to use it against Alastor]. The weapon holds all properties that have ever been attributed to the weapon "Excalibur" (or its counterpart in any language) or weapons that were inspired by it, throughout humanity's past, present and future.

Name: Excalibur, Caledfwlch, Kaledvoulc'h, Caliburnus Escalibor, Excalibor

Origin: Monarchverse

Age: The physical weapon is only a few seconds while "dream" has existed for billions of years within Alaya

Classification: Great Dream of Humanity

Wielders: Chrysaor | None

Powers and Abilities:  Light Manipulation (emits a light in all directions that blinds and burns enemies), Empathic Manipulation (the light it emits inspires hope in the wielder's allies and terror in their enemies), Fire Manipulation (the weapon can be enveloped in flames), Statistics Amplification (grants its wielder vastly increased strength, speed and durability), fulfills the qualifications of any weakness its target may have, Spatial Manipulation (the weapon can cut through space itself), Death Manipulation (even a single cut will kill the victim), Durability Negation and possibly Resistance Negation (some of the beliefs imbued in the weapon are that it can cut through anything and that nothing can defend against it), Regeneration (None for the physical weapon, the concept is Mid-Godly as even if the dream is conceptually erased Alaya will restore it), Immortality (Type 8, will always return as long as Alaya exists), true form is Non-Corporeal true form as it is just a dream, likely many, many more (due to its nature, it contains any and all attributes of any weapon known as or inspired by Excalibur throughout all of human history)

Attack Potency : At least Small City level (merely the light emitted from the weapon burnt several Lesser Chaosborn to ashes instantly, cut Alastor Prince in half), possibly at least Solar System level (as one of the 13 Great Dreams of Humanity it is created and empowered by Alaya and is one of the most powerful weapons it contains)

Speed : Varies on the user, Light Speed with its light

Durability :  At least Small City level, possibly at least Solar System level, In-corporeality, Immortality and Regeneration make it difficult to destroy

Range : Extended melee range with the blade, hundreds of metres with its light

Weaknesses: Although Alaya records, recognizes and empowers it as a Great Dream of Humanity, it cannot be naturally manifested due to having never actually existed, requiring reality to be altered to manifest it (for example, through the ability of Markus Adams). While it has the ability of any weapon (real or imagined) ever known as or inspired by Excalibur throughout humanity's past and future, its power cannot exceed that of Alaya's own.

Notable Attacks and Techniques:

Radiance: The weapon can emit a light that inspires hope and courage in the minds of the wielder's allies and inspires terror and despair in the minds of wielder's enemies, as well as burning them to ashes.

Death: Excalibur can kill with a single cut.

Statistics Amplification: The wielder of this weapon gains vastly increased strength and speed.

Weakness Embodiment: Excalibur has the ability to take advantage of any weaknesses its target or their defenses may have - e.g. against a vampire it would qualify as sunlight, against a werewolf it would qualify as silver, against a being that could only be harmed by a single weapon it would qualify as that weapon, against a ghost it would qualify as a spiritual weapon, etc.
