Black Hole

The Black Hole is the former prison and later headquarters of the Tzitzimime.

Description
The Black Hole's exact dimensions are unknown. The Tzitzimime live in an enclosed space within an actual black hole, protected (or imprisoned) by magic. Their palace is shadowy and dark, full of tree-like pillars made of human bones. Itzpapalotl has a small laboratory area in her throne room (though no throne, oddly enough), which is also equipped with a viewscreen made of energy. Presumably the Tzitzimime have their own quarters.
