Abomination is intended for use with the Strain basic system, but may be used with any system to create character backgrounds and weird adventures.
Abomination provides options for randomized character background elements to help form character concepts, and Aberrant traits that allow players to transform those characters into alien species.
Abomination also serves as a toolkit for Game Masters, starting with a map generator that creates a webwork of areas that may be above, below, or within each other. The GM may then use the location generator in each of these areas to create environments that range from the mundane to the bizarre. And finally, the creature generator exists to spawn unreal inhabitants into this strange world.
