Ceratos

Ceratos is a strange being from the Far Realm, and one of the oldest creatures in the world. He's considered an Elder Evil.

Appearance
It is said that Ceratos looks like a massive skinless sphere of flesh covered in mismatched eyes, mouths, and tentacles.

Background
Ceratos left the Far Realm and arrived to Exandria before the Founding, reveling in the primordial chaos. However, when said chaos was divided into the four Elemental Planes, Ceratos retreated underground, their many minds unraveling as they entered a nightmarish slumber.

A long time after, Torog's digging woke Ceratos. Longing for the lost chaos, their now separated minds started to work, sending thoughts and offerings of magical power to whoever could create chaos in Exandria. Ceratos assures that chaos brings clarity and destruction begets rebirth, and the truth is that they expect to one day regain their full power through these methods.

In addition to the actual followers of Ceratos, a few sages who study ancient entities are aware of the existence of this being, considering them dangerous, and that dealings with them can only bring madness, plague or death.

Trivia

 * Ceratos' name derives from the Latin prefix cerato-, meaning "horned" or "horn-like".
 * While Ceratos is considered a Chaotic Neutral being, they are part of the group known as "Elder Evils". However, it is possible that this name was created by the sages who study them, and that they don't necessarily define the alignment of each of these entities.
