47 I've been reading a Dwarf Fortress let's play recently. The overseer of the fortress decided to embark in a savage evil glacier with a volcano. It periodically snows frozen elf blood, and there's a reanimating effect there- which means that anything that dies pretty quickly zombifies itself. As such, the surface of the glacier is overrun with zombie migrants, merchants, pets, and a few kobolds. At least, the parts that haven't been flooded with lava.
