Meryet occupies a doorway as if it were a measuring instrument: broad stance, shoulders squared, and feet planted slightly wider than comfort requires. They lean their weight onto the balls of their feet when waiting, ready to step toward a leak or an argument, and seem only dimly aware that people make room for them. Their skin has the matte, sun-burnished texture of fired clay; their close-cropped hair is threaded with pale mineral dust that never quite washes out. Their eyes are dark amber, bright and intent, and their heavy brows lift whenever someone gives a number without showing their work. Their movements are economical, with a builder's habit of testing each foothold before trusting it. Unexpectedly, they keep a tiny folded paper theater in a protective tin and set it up for children during long negotiations.

Meryet is patient with honest ignorance and merciless with confident carelessness. They can be warm and funny around children or tired workers, yet stiffen into procedural formality when anyone disputes a measurement. They genuinely want peace, but their certainty that careful records can prevent cruelty sometimes blinds them to grief that cannot be quantified.

Meryet was born in a Serekh family of well diggers and learned to read water by listening to stone. In their twenties, they took a post repairing the old cistern at Kett's Dry Cut, where a failed retaining wall collapsed during a flash flood. Meryet had insisted the wall was sound, trusting an inherited plan over the warning signs in the mortar. They survived by hauling a trapped apprentice onto a roof, but the apprentice, Dast, lost the use of one leg. That failure changed Meryet from a gifted builder into a relentless recorder: every measurement, repair, and disagreement went into a shared account anyone could inspect. During the seven-year drought, Meryet designed a set of linked cisterns and scheduled releases among three rival oasis towns, preventing the strongest town from taking the whole supply. They still exchange letters with Dast, now a teacher of practical arithmetic, and with Givra, a canal keeper who once opposed them and now guards the records. Their current crisis is a suspiciously clean drop in the common reservoir, while each town accuses the others of siphoning water. Meryet's own notes may prove that the celebrated allocation plan has a flaw.
