ARRHENIUS | An Icecore Roleplaying Game
ARRHENIUS is a narrative-based adventure, exploration, and combat tabletop roleplaying game that places players into the boots, hide wraps, and synthetic skin of humanity’s far future descendants as they try to make it through the harsh and unforgiving world of the next ice age in the year 100,000.
Play as the nomadic ekavir, the subterranean dorrem, the muters of the great continental dome cities, the digital humans known as ozzits, or as scabs, the scavengers of the fallen megametropolises.
