Temporality
This d20 roleplaying supplement provides rules and tools for adventures involving time travel, reincarnation, and branching timelines. It introduces the Continuum, an organization that prevents separate Flows from merging, along with guidance for using existing spells across different eras. The book also includes new feats, magic items, organizations, villains, monsters, and Havens—safe areas of the Material Planes that are replicated through time travel. These elements support campaigns built around altering events, exploring alternate histories, and developing characters shaped by temporal changes.
