Esther raises her eyebrows. "This will take a bit. Let me prepare my exposition."
After a few seconds, she starts in on her exposition, conjuring illustrative illusions as she does so. "YISUN divides itself. The gods are born. Reality comes into being. The gods create angels, devils, humans, and sundry other races known collectively as servitors. These four categories are known collectively as inheritors. Then, the gods die, leaving the firstborn angels, the Primes, to guard Throne." She rotates her hands illustratively. "Pass a few kalpa. A human is born. His name is Zoss. He is a master of magic, and of dark science, and of the arts of war, and most importantly, he is royalty. True royalty. Through his science he recovers a fragment of the true name of YISUN; through his magic he wields it to breach the walls of Throne; through war he slays the Prime Angels; and because he is royalty, he drags the rest of the Name from Metatron's dying lips. He becomes the conquering King."
"With the firmament breached, it was not long before others came. They were the ultimate masters of their kind. Heroes, magi, poet-kings. They who inherited God's final works, and would seek to rule over them. They gathered in Throne, the dread masters of the universe, who sought ultimate hegemony. The Demiurges. And thus did the conquering King become the ruling King."
"The demiurges rebuilt the works of the gods, and bent them to their will. They forged bodies for the lesser angels. They bound the devils and stole their numinous secrets. For a time, they were content to live apart from all other worlds, a society of virtuous philosopher god-kings. They coaxed many secrets from the universe, and lived their days in enlightenment, art, and song. It was a fat age, ripe with learning. It was not to last."
"That is where your Key comes in."
"The Demiurges were warrior-kings at heart. They built themselves weapons - capable of ripping through reality and bringing them wherever they wished. And so they conquered, until they had conquered all that was. Heaven was already too crowded; soon the entire Wheel was not enough. At first they pretended their war was civilized, but then their singular hunger for dominion consumed them. They went mad. Worlds burned."
Esther shakes her head, dismissing her most recent (disturbing) illusion. "Anyway. The war for dominion had seven victors. The last of the Demiurges. Seven sovereigns, seven lords of infinity. They made a pact: the Pact of the Seven-Part World. To each, 111,111 realities."
She pauses to breathe. "Sorry, that was all backstory. The proper exposition begins now."
