Broad steps ascend to open archway at top lined in smooth malachite and swarming with hundreds of trilobite fossils. Damp stairs lead down into darkness.

• Trap: Two trilobites are worn to a shine. Pushing them deactivates trap for 5 rounds. Pressure on fourth step down turns stairs into ramp. DC 15 DEX or slide into 20' deep trapdoor pit at bottom (2d6).
