Drow

The Drow are elves with skin as dark as Onyx, that originate from an alternate plane known as The Underdark. They have access to a a particular brand of poison, as well as a mind controlling fungus. They seem to be faithful to a Spider Goddess known as Lolth, and are considered by the Magistery to be a war-mongering race, and therefore, intolerable.

During our Investigation of Valas, we learned some interesting facts (see Game-Summaries:2/16 Recollections):

They have the ability to mark opponents with Faerie Fire for future pain.
They have been hiring Solace's own impoverished citizens for labor
They have the ability to speak Common (why did I bother to Comprehend Languages?!)
At least some of the Drow seem to be working under duress, and the threat of death
There home seems to be a place called Menzoberranzan
