Ruins of Blackthorn

Publisher's blurb:

This town has seen better days. Most of the buildings have began to crumble, walls and roofs falling in. Moss and weeds have also overgrown the cobblestone paths and started intruding into the remains of the houses.

Many of the buildings hold stairways down to storage basements or further rooms below which also connect up to the towns sewers. In the subbasement there are multiple rooms which are still semi-lived in including a secret shrine.
