The narrow maintenance tunnel takes longer than it should to travel and ends in a sealed vault door. Inside is a small spherical room that glistens with an opalescent sheen. Small nozzles dot the floor and pairs of copper probes cover the ceiling. The west wall is a lattice work of holes, revealing a passageway beyond. Every turn the chamber slowly begins to fill with aerosolized metaline from 3.9 and electricity slowly arcs across the ceiling. The metaline in this room combusts at 1/10th the speed as a shielding malfunction has allowed a temporal anomaly to manifest in the wall. The combustion still causes 3d10 damage, but is very easy to avoid if the party leaves the room.
