Soulash

You were once the god-king of the Dreamworld, but you were dethroned by a new pantheon of gods. Mortals have forgotten about you. Your powers diminished and eventually, you had to go into hiding. You spent centuries scheming your revenge. With an ancient artifact, you tore the veil between realms and invaded the mortal world, but at the cost of your physical body. No god has set foot here for eons, but you changed everything. Soon new gods will come for you and the world will burn.
