The Living Building
This roleplaying supplement presents a strange, circular building that grows and changes as characters explore it. It includes background and descriptions, a sample floor plan, room-content tables, hazards, guidance for running the location, and creatures and mutations suited to its interior. Designed for Mutant Future and other science-fiction, fantasy, or post-apocalyptic games using Basic OGL rules, the material can be adapted as a changing adventure site for different sessions.
