Include a new tab for lore. This can be a catch-all for historical world periods and events, myths/legends, artefacts, and more. Important for when characters learn about the history of the world, or come across artefacts like the Vestiges of Divergence in Critical Role and need somewhere to compile this information.
Lore can be cross-referenced with locations, characters, factions and quests.
For homebrew worlds, this could also act as a repository for information on the Pantheon (may be more thematically accurate than “Factions” or “Characters” where these deities may currently reside.
