When humanity falls, four powerful industrial and financial dynasties form a covenant called Elysium, after the meadows of eternal Spring of Greek mythology. Deep in the bedrock, they build the enclave named Elysium I, designed to weather the long atomic winter.  Now, generations later, Elysium I is a gilded prison, a lonely outpost in a sea of quiet destruction. Fear and suspicion grow unchecked, and the four Houses fight on each other over the dwindling resources that remain. A force of Judicators has been established to preserve law and order in the enclave.  You are one of these judicators. It is your duty to investigate all crimes, but never forget that your strongest loyalty is always towards your family. When humanity sets foot on the surface again, it shall be your House that leads the way into the new dawn.  Mutant: Elysium is the third major expansion to the award-winning Mutant: Year Zero roleplaying game. This game tells the origin story of the enclave humans, seeing themselves as the last torchbearers of human civilization. The four Houses of Warburg, Fortescue, Morningstar and Kilgore struggle for power in the Elysium I enclave, oblivious to a rising power that threatens to end their reign forever. Mutant: Elysium can also be played as a stand-alone game.
