You tell the story.
Arcane Compendium conjures the rest.
Keep the whole story in view as it grows — and get a guiding hand whenever the next page feels blank.
Ahollow-faced scribe who trades in forbidden histories — keeper of the Ember Marches' oldest secrets, and the party's uneasy ally in Chapter II.
Gaunt, wrapped in travel-worn robes the colour of old parchment. Where a face should be, only shadow — and the faint smell of dried ink and candle smoke.
A place for everything your world holds.
Four pillars hold the whole tome together — organise, conjure, reveal, and recall.
A living page tree
Every NPC, location, faction, and quest is a page you can nest, cross-link, colour-code and reorder — then lay across the ages on multiple timelines.
Lore that knows your world
Summon an NPC, faction, or quest and it arrives already consistent with what you’ve written — drawing on the pages you already have, so you never start from a blank page.
Reveal the world in its own time
Set who sees what, page by page, line by line. Keep the twist hidden, then unveil it - to the whole table at once, or to one player at a time.
Ask your world anything
"Who owed the Pale Crown a debt?" Semantic search finds the half-remembered detail by meaning, not keyword — it surfaces the page even if you never wrote those words.
Summon the perfect entity, one that's lived and breathed in your universe.
Arcane Compendium reads the surrounding lore first, then writes an NPC, faction, or quest that honours the debts, grudges, and history already on the page.
The detail you half-remember is one question away.
The best stories are long — too long to hold in your head. Search by meaning, not exact words — the Compendium listens to any question and finds the pages that actually answer it, ranked by how closely they fit.
The adventure unfolds. The compendium observes.
Record your game and Arcane Compendium listens — turning hours of play into a clean record, then offering to fold what happened back into your world.
Maelith: The archive was never yours to read.
Kael: Then why leave the door unlocked?
The party confronted Maelith over the stolen archive and struck an uneasy bargain — safe passage through the Sunder Vale for a page of the Pale Crown's ledger.
Add: “Struck a bargain with the party in Chapter II — safe passage for a page of the Pale Crown's ledger.”
From blank page to living world.
