Lady Thistlewane's lantern: all of them, at a price
A Voice is a named NPC whose personal arc the players have resolved well. Each character's personality entry says exactly what earns their Voice. Typical Voices: Tibby, Valentin, Kael, Ione, Wren, Pip, Nassari, Lisette, Lu, Talonrook, Tullus, Imbraham, Kianne, Plargg, Uvilda, Jadzi, Hale, Quillon, Odessa, Barnaby, Rubina, Hofri, Shuvadri, Breena, Selka, Fain and others.
At noon on election day, as the seal fails, the names must be read aloud in the Hall of Oracles by people who remember them. Murgaxor and Extus are trying to open the Book at the same moment, so the Roll Call is fought for, line by line.
12+ Voices and 250+ names: Restoration. The year returns to history. Families remember. The snarl is shared lightly across every mind that now remembers it, and no single person ever has to hold it again. Marrow signs his own name and rests.
6-11 Voices: Restoration with a price. The list is completed only by Lady Thistlewane's lantern (her price comes due) or by a player giving up their dearest memory.
Under 6 Voices: someone must carry the snarl. See the Five Endings.
Tell the players the tally at the end of each school year, in-world: the Book writes it.
