Hey everyone!
Can't believe we're already onto part 5 of this year long collab with Kelfecil and Demetrius
Paid Heroic Maps Supporters - you'll find the supplement and regional map (plus the battlemap, though that's also attached at the bottom for everyone) here!
Check out the rest of the Broken Expanse Collab!
The Viridian Fen glows from its center outward, where Lake Verdigris spreads green light through mist, flooded ruins, and broken channels. Its waters are dangerous, though they may also be one of the few forces in the Broken Expanse capable of slowing the blight when treated correctly. Travelers come seeking relief, samples, cures, or profit. Many leave sick, changed, or not at all.
Across the basin, old systems continue to fail. Mired Abbey still holds traces of the rites once used to purify the lake’s water, while the Red Cyst pushes blight corruption through the mountain edge. Glimmercap Woods blooms with strange fungal color, the Umbral Merchants collect samples under masks, and Stormtower remains sealed against everything below.
The region’s featured battlemap focuses on the ruined shoreline of Lake Verdigris, where commoners, merchants, altered animals, surviving monks, and fungal creatures can all collide around the same dangerous water.

The Viridian Fen is the fifth release in The Broken Expanse, a location-focused mini-setting built around toxic water, failed purification, lake-born mutation, and blight resistance. This release explores a basin where the blight does not spread cleanly, because Lake Verdigris changes how corruption behaves across the land.
Rather than presenting a fixed adventure path, this release provides a fully developed region centered on dangerous resources, unstable healing, fungal growth, ruined water systems, and cautious outsiders trying to understand what can still be recovered. The featured battlemap focuses on a mist-covered lake shore where samples, rescue attempts, and sudden encounters can all unfold at once.
This material supports open exploration, repeat visits, and player-driven outcomes. The Viridian Fen is valuable because it may hold answers, and dangerous because those answers are never safe to use.

The Broken Expanse is a collaborative content line created by Kelfecil’s Tales, D&Demetrius, and Heroic Maps, developed through coordinated writing, regional cartography, and battlemap design. Each release expands a shared region one location at a time, keeping the setting modular and table-ready.
The content is system-agnostic at its core, with optional guidance written for use with 5E. Skill checks, encounter structures, and original blight creatures are provided as tools rather than requirements, allowing Game Masters to adapt freely.
