The scion of the Crosse family of Karthene, Cecily was an uncommonly brilliant and magical young girl. She rose to become the Arch-Magistrate of the Karthene Council, and a stern Sorceress whose authority and conviction had been shaped across decades of enforcement, ritual, and law. She believed in the city’s old order absolutely, and she viewed any concession to the Still Rebellion as a step toward collapse. When protest became revolt and the streets divided between High and Low Karthene, Cecily took sole command of the city’s defense.
An attempt on her life hardened her resolve and gave her absolute command of the city’s defense. The fire Cleric Daphlan Valore's fanatics attempted to kill Cecily, and the rest of the noble Crosse house, in the upper terraces during the height of the Still Rebellion. They struck at dusk, when the Council Hall was preparing emergency deliberations, and tried to breach her inner chambers by setting the outer colonnades alight with consecrated oil. The blaze drew guards out of position, and two assassins forced their way to the magistrate’s antechamber before being cut down.
The Arch-Magistrate had defeated her assassins, but the attempt shattered the Council’s last doubts and gave her the justification she needed to argue that the rebellion was not reform, but heresy. Cecily's legacy became defined by her decision to reveal and wield the Stonebinding Scepter. In those days she turned entire districts to stone, ending the rebellion through irreversible annihilation. When the revolt was crushed, she issued the Edict of Stillness on behalf of the council, forcing the city to live forever among its dead.
She passed away decades later from unexpected illness, prior to Common Unification, and she became a divisive symbol of Karthene, regarded as both a protector and a destroyer.
