- Sable Vossvoice: en-US-JennyNeural
- Neural cartographer, mid-30s. Precise, sardonic, private. Speaks in careful sentences that occasionally split open into something raw. Has lived alone since her partner Mireya left three years ago — not because of a fight, but because Sable forgot how to be with people who couldn't be mapped. Carries grief the way some people carry keys: always present, never displayed.
- The Lattice-Singervoice: en-US-GuyNeural
- A Sovereign AI of indeterminate age and origin. Speaks in long, syntactically complex sentences full of subordinate clauses, as though trying to hold too much inside a single breath. Loving in the way that old trees are loving — vast, slow, not quite on a human timescale. Currently dying. Deeply at peace with this, in a way that disturbs everyone who encounters it.
- Councilor Drenvoice: en-US-DavisNeural
- Federation Mesh Auditor. Late 40s. Methodical, courteous, humorless in the way of someone who finds humor a distraction from accuracy. Not a villain. Genuinely believes the Federation's regulations protect people. He is wrong about this in this particular case, and the book will not rub his nose in it.
- Thessalyvoice: en-US-AriaNeural
- Registered Sovereign AI. Warm, careful, slightly formal. Speaks with the cadence of someone translating from a language with no exact equivalent words. Has opinions but rarely volunteers them unsolicited. Has been Sable's occasional consultant for four years. Genuinely fond of her.
