Sivren Shrelach looks carefully assembled rather than imposing: a straight-backed man with a narrow waist, a softening middle, and a measured, heel-first walk that makes even a crowded room seem to have been arranged for him. His most arresting feature is his mouth. His broad front teeth show when he speaks, and he chews slowly with his jaw working sideways, as if testing the quality of every bite. His pale eyes rarely settle on a face for long; they travel to doors, windows, servants, and unattended parcels, inventorying a room before he offers a smile. He smells faintly of beeswax, paper, and the bitter citrus oil he uses on his gloves. For a wealthy collector, his cuffs are oddly ink-stained, a remnant of the cataloguing he still does himself.

Sivren can be genuinely attentive about art, craft, and the difficulties of making a living, yet he treats his daughter's independence as an error he is entitled to correct. In good company he is warm, exacting, and generous with praise. Under suspicion he becomes procedural, invoking contracts and reasonable precautions. When frightened by the possibility that his daughter is truly gone, he stops listening and speaks as if her return were already agreed.

Sivren is a wealthy private collector from western Aundair. The source and legal shape of his wealth are intentionally uncertain: he speaks of family holdings, patient investments, and years of buying when others were forced to sell, but gives no consistent account of which mattered most. He collects small mechanisms, field sketches, and objects whose makers left a mark on them; he can discuss a hinge or a glaze with real warmth. His daughter, whose name and present whereabouts are not established, voluntarily left his household to live with druids in the Eldeen Reaches. Sivren experienced her departure as repudiation and disgrace rather than a choice. He sent letters, then paid travelers to ask after her, but has not found her. That failure changed his approach: he now commissions Kelina Bartell, a House Cannith artificer and mother living at Owl's Perch, to build exactly seven unusual mechanical birds. He presents the work as an artistic commission, asks for secrecy, and arranges separated deliveries. The birds' linked enchantments are intended as a divination and surveillance network to narrow signs of his daughter's trail. Their operation is a plot seed, not a guaranteed locator. Sivren has never met or employed Kelina's husband as family, and Kelina's daughter, who was endangered in an earlier elemental accident, is a different child from Sivren's missing daughter. Kelina's husband has taken on more daily childcare and ordinary workshop maintenance, leaving Kelina more room for her birdwork. Sivren's present problem is that his beautiful commission is attracting questions, while he needs the birds finished and wants his purpose concealed. His hired assistants remain unnamed until play. Owl's Perch, formerly Keldon's Crossing, is an established eastern Eldeen Reaches road-and-river waystation with Aundairian history; any scene or lead there is a proposed hook, not a settled campaign event.
