|Exterminator in heavy enviromental gear|
The exterminators of the City are a special breed, as hard-bitten and courageous as any adventurer. The ones deserving of that appellation are not the day-to-day workers in the private pest control business (though some of them are tough cases, too), but rather the highly trained and perhaps a little crazy men (and few women) working for the Municipal Department of Animal and Pest Control.
Escaped familiars or the occasional wandering monster from out of the wilderness are the sort of calls that will bring out the men of the MDAPC, but their work a day grind is the monitoring and clearing of the various subterranean areas beneath the City. The City was built on swampy land crisscrossed by creeks and streams. These swamps were drained, and many of the waters directed underground through tunnels. Add to these waterways the sewers, steam tunnels, and subway stations that support the modern city--to say nothing of the occasional underground structure built by the Ancients. All these subterranean environments support life.
In the upper levels, one mostly encounter creatures which may have wandered down from the surface, or vermin swarms, or larger than normal specimens of such. Dangerous fungi are not unknown. Here the exterminators must also be careful to respect the ghouls and give them wide berth.
In the mid-levels, or in wetter places, various slimes, oozes, and molds are found. These strange life forms are born of the effluvia of industrial alchemy, the sludge of botched thaumaturgy, or the strangest flourishes of Nature--or possibly all three. Control of these lifeforms requires special preparation and often protective garb.
The lowest levels present the strangest and most eclectic challenges. There are prehistoric holdouts evolved (or devolved) to hideous, blind forms in eternal darkness. There are chimerical creatures produced by the decadent sorceries of the Ancients. There are even extraplanar visitors trapped their for millennia, summoned by prehuman wizards, and held behind eroding wards.
