The Rat Race is a Plague of Ratkin based in North America. Most humans estimate that the brown rat first came to North America in 1775, and for its Ratkin kin, this revolutionary spirit has never left. These American Rats are crazed, deranged, and violent. They have no matriarch, instead heretically believing in a "Great Rat God" that will lead them to victory in the Apocalypse. Unsurprisingly, many North American Ratkin stay away from these extremists, although many that refer to Rat as "he" most likely half-subscribe to this philosophy.
