Eldritch/Ancient ones.

Eldrich creatures are said to originate from the inky darkness of the night sky. They vary greatly in appearance, from simple eldritch minions to supposed elder gods. Their motivations are wholly unknown, but it is speculated that there are different alliances with leaders who enjoy acting out their own chaotic plans... assuming there are any plans. They only seem to appear when summoned or called upon and rarely appear on their own volition. Because of this they tend crop up in the darkest corners of the land, usually brought forth by cults or experimental spell casting by people seeking greater power.

When they do appear and take hold they usually influence their surroundings with eldritch powers, which usually consist of changing and corrupting their targets into forms they see fit.  Though this power can usually be countered or resisted.
