The Outsiders

Summary
The Outer Entities are a group of extradimensional beings from the world Xaria. Originally believing themselves to be the most powerful beings in the universe due to their existence as extradimensional beings, they eventually came across some members of the 13 Kings who were entertaining themselves in this world. Although weaker in power than the Outer Entities, the Kings' ability to travel between different multiverses (something the Outer Once were at the time incapable of doing) showed the Outer Entities that there was something more than just their own world. In their attempts to get through to the other multiverses, they attracted the attention of Laciel Monarch, who appeared before them. Driven to rage by the thought of something greater than themselves, they challenged him and swore to kill him, to which Laciel laughed and asked them to try, giving them the ability to travel between the infinite worlds and the rest of the Oak by destroying all other life within each world. While this was originally simple due to their extradimensional states, the Outer Entities eventally came across a world of High Outerdimensional beings, and were all but annihilated.

The only surviving Outer Entities were the strongest of their kind, and are Nyjarilath, Lafgyuzm, Ysmrthil, and (more to be added).

Note: In the verse of the Oak of All Creation, there exists an infinite number of multiverses and universes that are referred to as "worlds". Each world has its own characters or variations of characters. However, no matter how powerful the being is within that multiverse or universe, they cannot enter another "world" without permission from Laciel or his proxies.
