Canis Lupus Verso, also known as the Arcturus Wolf, is an introduced inhabitant of the world Arcturus and a miracle of evolution. Arcturus Wolves are descended from common dogs abandoned on the colony in the 2300s and have since 'devolved', though that term is not entirely accurate. Over time the common dogs interbred with several introduced wolves and survived on the harsh world and features akin to Earth Wolves began to reemerge and gradually, a creature akin to the Wolf evolved. These 'Arcturus Wolves' are now an apex predator, living as a pack animal that hunt the wild Grand Horns, large, well defended and aggressive bovine like creatures. Arcturus Wolves are comparable in size, power and fearsomeness to Tigers.
