Pixies

Pixies are beings that usually appear as small balls of light, with slight color differences between Pixies.

It is unknown what exactly Pixies are or where they come from. They're not considered Abnormalities by most people, despite possessing similar mysterious origins to Abnormalities.

What is known about Pixies is that they appeared at the moment the world 'ended'. Pixies do not have the power to 'create' Abnormalities, but they do have the ability to transform spaces into places that attract or breed Abnormalities.

It is unknown who gave Pixies the mission to begin humanity on their path of suffering at the hands of Abnormalities.

Pixies are also a very violent and sadistic race, seen through the 'Tutorials', in which almost all of mankind was massacred.

However, Pixies are fair to those who entertain them and pass their tests. After all, the only reason that humans have 'abilities' are because of what the Pixies have gifted them for passing the 'Tutorial'. 

After the Tutorial, Pixies are rarely seen, except when making large-scale events occur, such as the sudden appearance of 'dungeons' around the world.

There is no human alive after the apocalypse that doesn't understand the mixed horror and opportunity that comes when dealing with Pixies.

While unknown to most people, the Lost Forest is one of the many places that Pixies natively live in, when not monitoring humanity directly.
