Marcus was a holy man that turned to cannibalism and dark magic after spending a period of time living amongst the Palanai natives. He eventually tries to kill the Heroes; believing that consuming the flesh of an immune would save him and serve as a sacrifice that would end the Kuru/zombie outbreak. In the failed attempt to kill the Heroes, Paradise Survival Camp is extensively burned; leaving the Survivors with no choice but to relocate to the Halai Village. After the Survivors move to Halai, they are given the option to pursue Marcus to prevent him from endangering anymore people. But he says he was simply trying to save everyone but then attacks the Heroes who are forced to kill him bringing an end to the madness.
