Sham's The Enemy Within
Ernst Gottlieb had reportedly been head of the largest criminal gang in Nuln, until sometime in early 2522, when he suddenly vanished. With his departure, the Gottlieb Gang fell apart and other, smaller gangs rose to prominence in the city. A year later, while serving as mercenaries in Heideldorf, the party encountered Gottlieb, leading a small band of mutants, himself reduced to merely a fleshy head with small arms and legs. He had apparently eaten some of Heinz Schiller‘s Chaos-tainted sonderwurst and mutated. Fleeing Nuln, he set out to get his revenge on Schiller and the people of Heideldorf, but succeeded only in causing mayhem that killed as many visiting outsiders as locals, not including Schiller. He was killed by the party, once they’d done away with the more able members of his band.
