Memento Mori is a folk-horror roleplaying game set in Europe in 1347. The Black Death is exacting its toll on Europe, and it will quickly exterminate a third of the population. The characters are a group of Drifters, infected people who come in contact with dark creatures from folklore due to their condition. With every new horror they experience, the characters will become ever less human and increasingly similar to the creatures they are fighting. Only the Dream burning within them can keep them alive. What will they sacrifice for it? 200+ pages in black and white, hard cover, A5 format.
