“You have been chosen for a great purpose! Task! Mission! Destiny!”

He shouted dramatically as countless worlds heard his every word, from the lowest peasants to the mighty entities in the lofty palaces in the Higher Dimension.

“All of you accept your destiny as a sacrifice to Daemon Sultan, Blind Idiot God, Primordial Demiurge, Azathoth!”

And then Apocalypse descended.
