The Codex of Twilight
A book with shadows of its own — protective, watchful, and inclined to follow Zamaria from room to room.
The Codex of Twilight is a volume of twilight learning that carries shadow-tinged energy of its own. It pulses in its corner, deepens its shadows when magic in the room turns dangerous, and snaps shut when it has heard enough.
It does not stay where it is put. It follows Zamaria downstairs and leans toward what interests it, curious even while its instincts remain protective.
Zamaria and Lyra Emberhart study it directly, returning to its passages on resonance.
