Sludge Troll

The lanky, greasy sludge troll always seems to look like they just slid out of a pool of noxious sewage or filthy swamp water, with their scaly hide dripping with oily fluids and crusty muck. While they possess the iconic underbite and tusks of the typical troll, their facial features are much more fishlike, with bulging eyes and fin-like ridges on their spine, brow, and forearms. In addition to possessing prodigious regenerative qualities, sludge trolls are immune to diseases, and as a result, they often wallow and lair in areas infested with sickness for additional defenses. Tunnels and sewage outflows are their favored places to lurk in ambush, particularly if these areas see lots of traffic from underworld denizens. Generally more stealthy and sneaky than the typical troll, a sludge troll roused to violence is as terrifying and impossible to ignore as any others of their kind.

Sewer Dwellers

While sludge trolls are often found dwelling in mires and bogs, they are also perfectly at home lurking in sewers and cisterns below urban areas. Their lanky limbs and ability to squeeze through smaller areas helps them navigate confines that might prove troublesome for other creatures of their size, yet sewer-dwelling sludge trolls are still careful to avoid attracting too much attention from those in positions of power in the city above.
