Umberweb is a drow city of Sekamina which can be found far below the surface nation of Varisia. It is considered an outlying settlement, with native drow displaying slight differences in dress, accent, or mannerism compared to the inhabitants of the capital of Zirnakaynin. Of all the dark elven cities, Umberweb has the largest population of driders. Only here does one find sizable populations of the much rarer female driders living in close proximity to full-blooded drow.
