The chronological and geographic reference for the series. Timeline, faction tree, place index — the index card I kept pinned over my desk for nine books, written down for readers.
Why this series exists, what I was reading while I built it, why the protagonist had to be a child, and the ending I almost wrote and threw away. Author commentary on a finished nine-book arc.
A scene cut from Whispered Dark in revision. Chelsea, Kate, a guitar in a storage room, and ninety seconds of a child laughing for the first time since Sanctuary. Non-canon, but I kept the file.
Kate Morrison's official DDI file fits on three screens. This is the other one — the private dossier behind the protagonist of nine books, including the childhood the books did not have time to show and the ending nobody else could have written.
The Hollowing, the Void, the Dominion, and the dimensional physics underneath nine books of cosmic horror. The lore document I never wrote inside the series, because the characters did not have time to read it.
