Armok

Armok, God of Blood, is the name of the creator deity in the lore of the original Slaves to Armok: God of Blood, and the in-game explanation for that game's random world generation:

"Armok, the God of Blood, is just about the only constant in these chaotic random universes. A general sense of conflict keeps Armok appeased - when the universe becomes too boring it is set on the anvil of creation to be reforged."

"The destruction of the world by Armok will arise inevitably in most game worlds. As civilizations spread and the frontier closes, the world will start to look homogeneous. Armok, looking upon this decadence in disgust, will reform the world. Basically, when the universe has become too boring, it will be changed."

"But who or what is Armok? ARMOK is the God of Blood…The Supreme God, he gives name to the game, his powers are literally endless…He creates and destroys whole Universes just for pleasure and fun. He enjoys watching death, destruction and, of course, blood run on his Universe…In an Universe, he can have billions of worshippers, while in another his existence might be unknown...but HE EXISTS. This cannot be denied, and allows to play almost any type universe…from a standard fantasy-type world to a “primitive”, stone age world…and, why not a “future world” with star travel? In fact, when Armok creates an Universe, he likes putting more than one planet in it!

Remember…Armok can control and destroy all other creatures, including the other, ”lesser” gods, but he usually enjoys watching civilizations grew, because he hopes that one day these civilizations will fight each other, and thus generate conflict and slaughter!"

Armok does not appear as a deity available for worshipping in Dwarf Fortress worlds, as his name is a throwback to the original "Slaves to Armok" and bears no direct relevance to Dwarf Fortress itself.

Name Origin

The name of the Dwarven God comes from the variable "arm_ok", which is from Tarn Adams's fantasy game, Dragslay. The variable was used to count the number of arms left, for inventory purposes. (Source)
