Animus Lumnisphere

The Animus Lumnisphere, a sphere of pure dark magic, is the source of all magic, in both the Human Realm and the Demon Realm. It resides within the Demon Realm.

Conflicts
Because of its power, demons compete to gain control over the Lumnisphere. With enough power from the Lumnisphere, a demon can ascend to godhood.

The demon Alvahdeus managed to take majority control of the Lumnisphere and became a god.

The demon Gal'Yakar decided to take a shard of the Lumnisphere to the Human Realm and share its magic with the humans to prevent Alvahdeus from reaching godhood in that realm and becoming a Supreme Ruler.
