Same kinda idea but changed some things around/fleshed it out a bit more. Will probably just proceed with this. 

Also figured it'd be a good idea to give context, this was my idea initially:
At the depths of nearly unreachable planes shrouded in darkness, the originators slept. Now awakened to turn the tides in the war against light and dark. Spewing darkness, they mold souls acquired in their innumerable lifespan into unfathomable creatures.
