Character · Book 4, The Gate of the Feral Gods
Princess Formidable
The youngest child of King Rust, sister of Prince Stalwart and Prince Maestro, and Katia's sponsor from the fourth floor: her first gift is one crossbow bolt, 1 of 100, that pauses a god's invulnerability if it hits the eye. 'I'm starting to think the sister isn't a huge fan of her big brother.'

Arc
Sends Katia an emergency silver box that must have cost a fortune — ten Bolts of Petrify Rock Class — the moment Maggie, sponsored by both her brothers, walks up to Carl in Chris's body (ch. 14). The bolt she sent Katia on the last floor, which strips a god's invulnerability for a few seconds, is not used on Emberus; Carl still thinks harming a god absurd (ch. 32).
