Added 2025-07-11 12:17:03 +0000 UTC

“Beneath the city’s backstreets lies the treatment works—a cavernous hall of corroded pipes snaking across vaulted ceilings, their joints leaking in rhythmic taps that echo off damp stone walls. A vast, murky reservoir stretches before you, its surface broken by rivulets of grey runoff tumbling in from sloping channels, while rusted grates creak underfoot.
The stench of rot and stagnant water mingles with the sharp tang of chemical cleansers, and every breath tastes of mildew and iron.
Scattered across the slick floor are scraps of straw, broken boards blackened by decay, and loose stones that clatter under cautious footsteps. Somewhere in the gloom, the distant hiss of pressurized valves threatens to burst into a roar — something is coming.”

Sewage Sump is a 38×37 map—a vast, echoing chamber of corroded pipes and dripping joints, where grey runoff cascades into a murky reservoir framed by rusted grates. In that immense pool, you’d half‑expect a colossal monster to rise—fortunately, it isn’t there… right?

This map, as usual, comes with a number of tiles to adjust the encounter to your needs and has been set up in our Foundry module to make it easy for you to swap between the variants!

We hope you enjoy it!
