Fel

Fel is a corrupted form of arcane, created by the mad titan Aman'Thar to fuel demonkind. Fel energy manifests as a ghastly burgundy color, and is arcane magic at its most corrupting.

Overview
Fel and blood are synonymous for demonkind, as they are one in the same. The most common source of fel in the universe is in the blood of demons, though it is not the only source. Fel magics have been infused throughout the Prismatic Dark, creating alien biomes and exotic weather patterns.

Entropic Fel
In some locations of the Dark, it runs rampant as entropic fel, living manifestations of fel energy most commonly found in fiends.
