A scullery maid of El Alcázar with a spy's knock (three soft, a pause, two more) and the steadiest nerves in the palace. The morning after the wolf night she slipped past the searches to deliver everything at once: Ilsa taken, seven guards dead by Otto's hand, Friedrich leaving for Eisen with a vow on his lips, and the Yellow Lady's summons.
He killed them. All of them. Seven. Then he was gone.
Kodai sent her back before she was missed. The crown in exile runs on exactly this: small, scared, and reliable.
