Wolfsbane Hollow (OSR)

From publisher blurb:

Shielded to the north by the Vurdfell Spine’s lofty peaks and protected from the Hordelands of the east by the Greatshadow Gorge, the town of Wolfsbane Hollow has persisted in relative isolation for hundreds of years. Seemingly a simple border town, a dark shadow hangs over this hard, rough settlement. For here, the rule of law is tenuous at best, and the mayor is but a figurehead. The true power of Wolfsbane Hollow is the shadowy thieves’ guild and their monstrous, bestial guildmaster who lurks in his lair carved from the fallen, mouldering bones of an ancient empire.
