Character Sheets are often treated as side documents: necessary, useful, but somehow separate from the campaign itself.
That framing breaks down as soon as continuity starts to matter.
In the current Delvus model, a Character Sheet is part of campaign state. It is not just a record of numbers. It is a living artifact that carries identity, survivability, equipment, notes, spell-preparation style details, portrait context, and the marks left by prior sessions.
That does not mean every sheet becomes an engineering diagram. It means the sheet stops being disposable.
Players benefit because the artifact they use at the table reflects the actual ongoing campaign. DMs benefit because continuity no longer depends on scattered files, memory, or after-the-fact reconstruction. The campaign benefits because a sheet can belong to a session history without becoming trapped inside a single scene.
This is also why portraits and presentation details matter more than they first appear to. They are not decoration layered onto a separate system. They are part of how the campaign remembers who a character is when the table returns.
