The Book of Fiends

Cursed by Athena, Arachnadia has become a very powerful and feared demoness. Her Abyssal lairs are collectively and rightfully known as the Demonweb pits. She usually collectively and rightfully known as the Demonweb pits. She usually takes the form of a large, 9-foot long black widow spider, though she enjoys appearing as an exquisitely beautiful female drow. Little is known about her aims, and only the fact that the drow worship of Arachnadia causes her to assume form on the Material Plane permits compilation of any substantial information whatsoever.

Areas of Concern: Poison, dark elves
Domains: Chaos, Destruction, Evil, Trickery
Favored Weapon: dagger


To regain his full complement of spells, a thaumaturge dedicated to Arachnadia must weave a delicate spider web from a length of string. He then wraps the web around a living insect, entwining the bug in a cocoon of thread. The thaumaturge crushes the cocoon in his fingers, smearing the resulting ooze upon his weapon of choice.
