The Solifugid Nest is a rough cavern where narrow tunnels converge on a larger central hollow marked by stone shelves, scattered remains, nest-like areas, and small side pockets in the rock. The map's open center contrasts with the constricted approaches, creating the sense of entering a lair where the inhabitants control every exit.

For a GM, that geometry is ideal for a swarm or predator encounter. Characters can spread out once they reach the chamber, but doing so exposes them to threats emerging from multiple tunnels. Side recesses are natural places for eggs, prey, treasure, or hidden creatures, and the central floor provides enough space for a mobile fight. In Shattered Star's Curse of the Lady's Light, the nest belongs to the sequence of caves around the monument. Outside the adventure it works for giant insects, spiders, burrowing monsters, or any creature whose lair should feel more dangerous the farther the party moves from the tunnel they entered through.
