Recipe: Dungeon Floor
The air in the Undermyr is heavy, not with the usual damp of the deep earth, but with a metallic, copper tang that clings to the back of the throat. Pulsing veins of bioluminescent red ichor trace the architecture of the dungeon, following the natural cracks in the obsidian walls like a diseased nervous system. Here, the traditional web-work of the Drow has been replaced by glistening, wet strands of solidified gore that vibrate with a low, rhythmic thrum. Deep within the Sanguine Vaults, the sound of rhythmic chanting competes with the skittering of many-legged horrors. The floors are slick with ritual runoff, and the light is a perpetual, sickly crimson. You are standing in the birthplace of a new terror, where the elegance of the Elves has been subsumed by the hunger of the blood-ritual, and the spiders are no longer mere pets—they are extensions of the cult's own circulating life force.
High Priestess Valthara, House Valen'dros
“Let the nectar of the weak feed the hunger of the many. In the blood of the fallen, we weave the future of our House.”

The life is in the ichor; the ichor is in the web.
