Under the Caustic River Ahnd

An OSR system-agnostic adventure set in the Undying Expanse, where a turbulent, caustic river melts organic material in moments. Beneath the river lie the decaying remains of a nefarious wizard’s lair, and opening a passage through it could bring commerce and prosperity. The adventure includes setting information for three villages, a hazardous dungeon that may collapse, six magical relics, fourteen new monsters, player handouts, an optional mutation table, and an aftermath section covering the consequences of the party’s exploits.
