Don Galir (PF2)

From publisher blurb: Last known hold of the dwarves in Ashlar, shadow-cloaked Don Galir lies hard against Lake Thraren dark, cold waters in a massive cavern buried directly beneath the human village of Wellswood. Dozens of wells, illuminating the lake’s dark, unknowable deep waters with faint shafts of light and link the lake below with the village above. Strange fungi and mushrooms grow around the lake’s shore and stranger fish dwell in its lightless watery depths. Humans and dwarves fish the lake and harvest these unique plants in an increasingly uneasy peace. Now the jealous attentions of the greedy lord of the village above fall on Don Galir and taxes slowly increase. The reclusive, secretive dwarves of the Erdikr clan work hard to fortify their hold and to attract more of their brethren to Don Galir while some secretly plot to regain their fallen dragon-infested holds lying far to the south. Don Galir stands in (or rather under) the human realm of Ashlar, but is easily compatible with virtually any fantasy setting.
