Aziraphale moved like a man possessed - though, of course, no such thing would ever be formally permitted. The back room of the bookshop was a maze of volumes, manuscripts, folios, and files. His fingers moved with practiced speed, brushing over bindings, flipping past coded symbols and celestial notations.
Crowley's voice from earlier haunted him.
"It's not just old. It's reacting … She's not afraid … exactly the sort of person this thing would choose..."
That last part was what worried him most, because there were stories. Records not stored in Heaven's bureaucratic archives but whispered between archivists. And worse - some that had been deliberately hidden.
He found the one he was looking for tucked between two binding fragments from the 14th century: The Index of Forbidden Texts (Celestial Revisions, Second Redaction). The parchment felt warmer than it should, like it remembered being burned.
Aziraphale blew off a fine layer of dust, cringing as it billowed. "Oh dear."
He flipped to the index. "Grimoire, Latin-rooted, celestial fragment, locked sigil…"
There. Page 173. He opened it, hands trembling slightly. Read. And went very, very still.
Codex Ardem Lux
Bound in ash and blood, anchored by Name, sealed beneath false scripture. Burned thrice. Returned twice. Last opened in Lisbon, 1755.
Beneath that: Witnessed by: Muriel, Azazel, and The girl who did not burn (human).
Aziraphale sat heavily into his chair. A human. Not possessed. Not damned. But marked by contact with divine intention.
He didn't like it - especially the bit about burning (or lack of).
The Codex hadn't chosen a vessel since 1755. That is, until now.
He set the book down gently, as if it might choose to vanish if startled. His hand hovered over the phone, hesitated. He didn't dial. Instead, he crossed to the window and stared out into the pale light of mid-morning. He pressed one hand against the glass.
He'd seen what happened when the wrong hands touched the right words. But it was worse when the right hands didn't know what they were.
"Crowley," he whispered to the world outside, "what have you gotten her into?"
