Armok, God of Creation, Debauchery, and Depravity, was bored of his two-dimensional world of chaos, destruction, murder, debauchery, undead, incest, drunkenness, ghost hauntings, demons, false deities, and heroes who died in a second, so he decided to stop recreating the same world again and again. He destroyed the world that was currently on, which was ruled by a goblin king who was also a vampire, and took old pieces of worlds long past. These pieces were of noble elves, human heroes, depraved goblins, drunken dwarves, and even sneaky kobolds, each of whom had appeased Armok in one way or another. Armok laughed, holding the pieces in his large tentacles, before throwing them across the street and into his neighbor's world.
This is the story of the civilization-killing, drunken, and idiotic peasants and their arrival unto the untainted land of Equestria, where they will live, and they will die, for it is Armok's will.
Praise unto Armok, Creator of Worlds and Destroyer of Minds.
This was written because of Dwarf Fortress. I love that game too much sometimes.
