The Night Wolf Inn

From the publishers blurb: The Night Wolf Inn is a sand box experience for 1st Edition RPG Gaming. It is a tavern and a universe unto itself; a place of powerful dweomers, secret doors, lost gods, hidden dimensions and dangerous artifacts. The Inn's mysterious backstory holds the sandbox experience together. The Night Wolf Inn fits snugly into any campaign, occupying only the space of its buildings and lawns. It is also intended to be fully customizable. Includes: Fully detailed maps and locations of the Inn featuring four floors, outdoor property, and extra-dimensional spaces. Partially detailed launch points into over twenty pocket dimensions and parallel worlds. Many new magic items, treasures, artifacts, monsters, demons, gods, NPCs, races, languages, and myths. Beautiful art. Player and DM versions of relevant maps. Player handouts. Quick reference cheat sheets.
