The peg-legged maintenance superintendent of Clearmountain Central Services had a problem. The recent round of earthquakes was barely noticeable on the surface, but it had wreaked minor havoc on infrastructure in the undercity. Chemical sensors in an underground cistern showed contamination by an unknown and potentially dangerous source, presumably ruptured and leaking into the pond as a result of the seismic disturbance. Pollution of a subterranean graywater pond was not itself an issue, but if it were to flood and back up into the main stormwater system...
Pepper and John Benson were joined by new hires Eddie and Gary on their expedition to the undercity to fix the problem. The underworld map suggested two angles of attack to the previously unvisited node: entry through the defunct subway station below the railyard, or entry through the old bathhouse in the northeast of the city. They had heard rumors from the Exploration Project that the bathhouse entrance would take them to the cistern, though the exact route was obscure.
Peg Leg gave the team some useful tools before sending them out: a spray tank of sealing foam (somewhere between caulk and insulation) and a thermal lance (a cool and incredibly dangerous cutting torch that used pure oxygen and an acetylene torch to ignite a tube full of steel rods as fuel). Then they set off for the bathhouse, excited to scout a new dungeon entrance.
