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.'

First appears: Book 3

Series arc

As of book 7. King Rust's youngest and Katia's sponsor since book 3, a voice demanding the failsafe in book 6; in book 7 five hours from the Venus station with marines, on a Nebular theory that the AI's insanity is contagious, then dropped upside down into Orren's office, told the failsafe is dead, and given four choices — Earth's surface. Her crew press the button anyway; Aryl goes dark; 'That orc princess was right', says Tagg; her fate is unknown.

Thread	Opened	Status
The Bolt of Ophiotaurus	B3 ch. 29	open · B6 ch. 69 — Katia lends the Bolt to Paz; he puts it into Ysalte's eye before his blast takes her head off, and it comes back reusable (ch. 72).
The Aryl system went dark when the button was pressed	B7 ch. 41	open — Formidable's crew pressed a dead button; at that nanosecond the previous crawl's system lost its tunnel node, which has never happened; its AI had gone silent during the sixth floor. Three cycles until anyone knows if the star is there.
The failsafe, and who is trapped in orbit	B6 ch. 49	resolved · B7 ch. 41 — Disconnected by Carl on Christmas morning (ch. 20); Formidable's crew pressed the button anyway and the Aryl system went dark instead (ch. 41). Formidable was dropped in the ocean (ch. 37).

By book

Princess Formidable in book 3 — The Dungeon Anarchist's Cookbook

Katia's sponsor from ch. 12, whom Carl privately identifies as King Rust's daughter; her one gift is the Bolt of Ophiotaurus (ch. 29). Grull, in her brother's voice: 'that magical bolt my cunt of a sister wasted on your friend' (ch. 33).

Princess Formidable in book 4 — The Gate of the Feral Gods

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).

Princess Formidable in book 6 — The Eye of the Bedlam Bride

A scroll of worship for Katia, so not on the ninth floor with her family (ch. 19); in the epilogue, in orbit, demanding the failsafe — 'I would die, too, you idiot' — and muted (epilogue).

Princess Formidable in book 7 — This Inevitable Ruin

Rust's third child, 'the one you need to worry about': five hours from the Venus station with marines, to trip the failsafe by hand on a Nebular theory that the AI's insanity is contagious (ch. 34). Dropped upside down into Orren's office in a spacesuit, told the failsafe is dead, given four choices, she picks Earth's surface: 'I hope she knows how to swim' (ch. 37). Her crew press the button anyway, and Aryl goes dark (ch. 41). Tagg says she was right (ch. 78); her fate is unknown (ch. 86).
