Ink is a blue-skinned Qumon with a narrow, alert face and silver horns that sweep back close to his skull, their ridged surfaces dulled by years of handling tools. His blue eyes have the clear, hard shine of glass beads. A purple tail curls behind him, usually threaded through a loop in his belt to keep it from catching on his work. He stands with his weight pitched forward over the balls of his feet, as if ready either to bolt or to lean over a page. He smells strongly of lampblack, hot oil, and bitter orange peel; he knows about the oil and insists the orange is for the books. His hands are usually stained with ink up to the knuckles, an unexpected mark on an artificer who keeps his tools meticulously clean.

Ink is careful with other people's pain but impatient with machinery that refuses to behave. He can be warm and gently funny with someone who is nervous, then sharply exacting when a powerful person tries to blur responsibility. He wants to believe that a truthful record can help, yet distrusts anyone who calls a story simple. When tired, he becomes terse and over-organized; when frightened, he starts asking practical questions as if planning a repair.

Ink was born far from Quadra Virex and has never had a reliable account of his early childhood. He remembers scraps: the rattle of a wagon latch, a handler counting people as if counting crates, and a woman beside him teaching him to make letters by tracing them in dust. Raxtorim's slaver caravan traded him between owners during a long passage through the interior. He survived by studying locks, wheel hubs, and the small failures that could slow a caravan without inviting immediate punishment. The formative break came when the woman who taught him letters was taken away after Ink tried to hide a note in a supply bundle. He learned that a written record could endanger its keeper, but also that silence left abusers free to tell the story themselves. He eventually escaped during a storm, using a bent axle pin and a torn harness to create a confusion of broken wagons. A family of itinerant repairers got him to Quadra Virex, where he took work mending presses and copying documents. He now writes a book about the caravan's abuses, recording testimony from other survivors with their consent. His current problem is that one account names a person who still has power in the city, and Ink cannot decide whether publishing it would expose the truth or endanger the witness.
