The Sky Beast is a giant being created by a certain infamous cult in a desperate desire to summon their patron deity known to them as ‘The Destroyer’. The Destroyer was a god whose abilities were made to match that of the Creator, but instead of creating, it would destroy and from the aftermath of its destruction would facilitate the rebirth of the universe.
While such a deity did not exist before, the Sky Beast was an attempt to realize their belief into reality.
What the Sky Beast actually is is an big black amalgamation of souls linked together forcefully. The souls desperately grab and claw at all things full of life and unknowingly drag those it touches into the same fate, only to grow larger and larger. Its outward appearance is something of a large orb-like being with innumerable arms and eyes.
It was manifested thanks to two young people—Entos, the bearer of the Dreamstone, and Kaara, who had the power to breath life into things that did not previously live. The cult regarded them as something of like the ‘Adam and Eve’ of their idealized new world.
There was a time when the Creator could have destroyed the Sky Beast, but she hesitated upon learning the true nature of it. She now lives with the guilt of her inaction.
