Aberrations

Aberrations, as a rule, are the common enemy of all creatures native to the Hourglass Cosmogony. They come from beyond the Hourglass Cosmogony, a place called the Void Chaos. Every known form of life but aberrations rely in some fashion on the pure power of creation of the Primal Chaos. They do not. Instead, they seem to take anything they can from our cosmogony, deconstruct it into something similar to the Primal Chaos, and take it away, presumably back to the Void Chaos that they come from.
