01 · Cast
Characters are more than names in a sidebar.
Profiles cover history, psyche, appearance, voice, skills, relationships, arc and notes. Character arcs anchor the transformation to concrete chapters and scenes.
Connections make the social structure visible: who loves, mentors, rivals, owes or betrays whom. The ties you draw hold across every book in the universe.
Character profiles and gallery
Build it once. Remember it everywhere.
02 · World
Places, powers and objects keep their context.
Locations collect scenes and images. Factions carry membership and crests. Items record who holds the object and where it matters. Research files sit beside the manuscript; glossary names light up in the prose.

03 · Continuity
One universe can hold a shelf of books.
Universes group books and worldbuilding into a shared continuity — a series bible for everything the sequels must not contradict. Museiki turns the same living data into an encyclopedia you can read, search and export. There is no second bible to maintain.
One universe and everything in it
