Not all of the putrid, slick goo that oozes from openings in the floors and walls is merely disgusting. Some of it poses great danger as well. While slime has no intelligence, it is attracted to the heat that bodies generate. This ichor will literally drain the life from its victims, as heat is what it uses as food. No magical properties have been found to exist within the slime, but nature is often a magik unto itself.^{W1manH 32}
