A Vermin Keeper is a prestige class of the Underdark. Whether formerly from the Realms of Above (as the lands of Faerûn are called in the Underdark) or life long denizens of the dark places, Vermin Keepers have mastered the control of vermin creatures. Insects, spiders, scorpions, worms all are subject to the orders of the Vermin Keeper. Unlike the Arachnomancer, Vermin Keepers do not necessarily worship or even enjoy the presence of vermin; mastery of what one fears drives a number of these druidic spellcasters to this discipline.
