Jek has the compact, forward-leaning silhouette of a bird that has spent years bracing against harbor wind. His soot-black feathers are slicked flat by salt spray along his shoulders and split into rough, rain-frizzed tips around his neck. A pale line of down runs from his beak to his throat like spilled chalk. He takes up little space until he decides a passage is closed; then he stands with his wings slightly out, making his narrow frame seem like a barred gate. His gaze is bright and beadlike, always flicking toward hands and cargo labels. Unexpectedly, he keeps a tiny, immaculate paper flower tucked into his breast feathers, replacing it whenever the harbor damp ruins it.

Jek is scrupulously fair about fees but quietly bends rules to protect tired workers. In a routine exchange he is dry, brisk, and procedural; when someone is frightened, he becomes attentive and surprisingly patient. If accused of causing harm, he turns coldly exacting and demands proof, though guilt makes him overreact to even harmless mistakes.

Jek was raised among dockside kenku who survived by carrying messages, copying seals, and repeating whatever useful voices they heard. As a young runner, he worked the old ferry toll at a narrow channel. During a storm, the collector ordered him to repeat a warning that the floodgate was open. The warning was false, copied from a sailor's joke; a loaded barge struck the closed gate and several people drowned. Jek had not understood the words, but he had delivered them with perfect conviction. He quit message work and took a post collecting tolls, where every charge is written, witnessed, and counted aloud. He now works the Bellmouth quay, whose old tollhouse is said to have been built to keep the sea out. His former mentor, Sava, still insists the disaster was not his fault, while his sister, Neri, sends him requests for money from a neighborhood he refuses to visit. He is currently tracing a run of forged passage tokens that appear to have been made using his own old seal.
