From Discworld MUD Wiki
Mamie Olivia is a short, dark woman of indeterminate age. Small, bright eyes peer out from a nondescript face, and her lean body has been toughened to a teak-like hardness from wandering through the swamp. She is in good shape. She is standing. You can't help but notice thirty warts upon her face. Wearing : a pair of hobnailed boots, a red flounced skirt, a plain white cotton blouse and a red head scarf.
Mamie Olivia is always in her shadowy tent on southeast Dead Man's Walk in Genua.
Mamie Olivia says with a Genuan accent: Yes, I can turn corpses into zombies. Only certain corpses, though.
