Toxic Sewer Wall Debris 2 TS-003 by Dungeon Blocks

Somewhere beneath the city, the walls have begun to weep — and whatever is growing in the filth below is not entirely natural.

• ✔ Resin terrain piece, printed fresh to order in the UK
• ✔ Supplied unpainted — primes and paints easily
• ✔ Compatible with standard 28mm–32mm miniature scales
• ✔ Works on the gaming table and as part of a display diorama

This is the Toxic Sewer Wall Debris 2 (TS-003) terrain block from Dungeon Blocks — a richly detailed modular piece depicting a crumbling brick wall section buried under a heap of corroded barrels, broken planks, and writhing toxic vegetation. The painted example shows the piece in vivid greens and sickly yellows, with organic growth creeping across the rubble in a way that immediately signals to your players: this place is wrong, and something has been festering here for a very long time.

Designed to sit flush with other Dungeon Blocks sets, this piece represents 5ft in standard 32mm scale. The 3.5cm square base fits neatly alongside your dungeon tiles and is compatible with standard 32mm and 35mm miniature bases. Whether you are building a sprawling undercity encounter or adding a single atmospheric detail to a sewer scene, this block earns its place on the table — and looks equally at home on a display shelf.

Well suited for adventurers who:

• Run urban underworld campaigns with sewer networks, thieves' guilds, or forgotten infrastructure
• Want modular terrain that builds into larger dungeon layouts over time
• Are painting terrain pieces for diorama scenes or display setups
• Need scatter terrain that adds genuine narrative weight to an encounter location

Encounter Hook:
The party has been sent to find a missing city inspector — last seen investigating reports of tainted water supplies. They descend into the sewer and find her satchel half-buried beneath a collapsed wall, the stonework cracked open by something that has grown through it from the inside. Whatever caused this is still down here. And it knows you've arrived.

Each block represents 5ft in standard 32mm scale and has a 3.5cm square base, making it fully compatible with standard miniature sizes and all other Dungeon Blocks terrain sets. The image shown is an artist's painted rendering — the block will be printed in your chosen base colour of grey or black FDM.
