The Silt Sink

The city's waste hides more than just filth.

6 roomssewereasy

A forgotten segment of the municipal sewers where the water has turned to a thick, black sludge. The masonry is crumbling, revealing ancient foundations beneath the modern city streets.

The air is humid and smells of methane and rot. Distant splashing and the scratching of claws echo through the pipes while flickering bioluminescent fungi provide dim, green light.

☠ Threat

Varkas the Bloated, a massive and mutated carrion crawler, stalks the lower chambers. Fed by the waste of the city and the offerings of the resident wererats, it has grown unnaturally large and fiercely protective of its territory.

History

Originally built as a private drainage system for a noble estate centuries ago, this section was sealed off after a series of mysterious disappearances. Over time, it was forgotten by city planners, allowing a small pack of wererats to turn the tunnels into a hidden sanctuary and dumping ground.
