Seshith is a lean, charcoal-feathered kenku with pale silver markings around the eyes and a narrow band of rust-red feathers across the throat. Their plumage is carefully maintained, though several primary feathers are tipped with copper dust from years of workshop labor. They wear reinforced scale armor beneath a soot-dark leather apron, with a compact shield fitted with brass hinges and a repeating crossbow-like mechanism. Their satchel is crowded with labeled components, tiny tools, folded diagrams, and polished fragments of colored glass.

Seshith is observant, wry, and intensely practical. They show affection by repairing equipment, remembering the exact sound of someone's footsteps, and quietly placing useful objects within reach. They dislike grand speeches but have a talent for making one perfectly timed imitation expose a liar.

Seshith was raised among the highland workshops of a traveling kenku makers' guild, where every craftsperson learned to listen before speaking. Their earliest teacher was an elderly locksmith who communicated almost entirely through borrowed sounds, and Seshith learned to distinguish a tool's proper use from the scrape, click, hiss, or chime it made in practiced hands. They became fascinated by artificers who could place intention into metal, wood, and crystal, and eventually apprenticed to a master armorer whose work supplied caravans crossing dangerous mountain passes. When a guild caravan disappeared after accepting protection from a supposedly respectable mercenary company, Seshith found evidence that the armor and weapons had been deliberately sabotaged. The guild elders wanted the matter settled quietly, but Seshith refused to let the dead become an accounting error. They rebuilt a damaged steel guardian from the caravan's broken equipment and set out to uncover who ordered the sabotage. Their investigations led them into adventuring, where every ruin is a workshop, every enemy leaves behind useful evidence, and every rescued traveler is a possible witness. Seshith fights to protect ordinary people from those who treat invention as permission to control others.
