Tharizdun

It is darkness unending, less like a god and more like another world. Life and death do not exist within Tharizdun, only utter destruction and madness. Even teh other Betrayer Gods treat this mad god with caution. In its endless imprisonment, Tharizdun dreams the infinite depths of the Abyss into reality, along with all its demonic legions. The Prime Deities had thought it locked away during the Founding until it nearly returned to ruin the world during the conflicts of teh Calamity.

Now, its chatoci mind has fallen into more frightful dreams, imagining nightmarish aberrations into existence deep beneath exandria. The Chained Oblivion's demented cultist work without word from their twiested patron, awaiting the Epoch of Ends when its freedom will be attained and all beings shall be consumed in deathlessness unending.
