The Web: Massive strands of silken webbing interlace this twilight void. Smaller webs festoon each strand, or drift softly through the air. Spiders of all shapes and sizes hunt throughout the realm, devouring victims brought in by countless natural transient portals. Native areana sometimes rescue inadvertant travellers, ransoming them or demanding a period of servitude. Drow have recently found their way into The Web and established several powerful beachheads; some areana have become allies, while others seek to exterminate the invaders. What the drow are only starting to realize, however, is that humanoid creatures mutate in the arachnoid plane, and many susceptible drow have already become driders.
