Underground River

This is a supplement designed to be used together with the Stonehell Dungeon by Michael Curtis. It connects the Nest of Otrogg from the Buried Secrets supplements with different Stonehell levels.

It is written for the Shadowdark RPG, but it should be able to be easily converted to other OSR-adjacent RPGs.

Note that this is meant to be a transitional area to flesh out some of the locations around Stonehell, it is not a fully-fledged dungeon.
