In their natural form, Asteris is a compact, long-limbed changeling with skin like smooth river clay, faintly pebbled across the knuckles and weather-dulled at the temples. Their jaw is unusually broad and folds inward when they smile; close observers notice small, crowded teeth and a habit of testing food with the front ones before biting. They move with the careful, economical balance of someone used to narrow gangways, keeping their shoulders angled as if making room for a passing crewman. Their unexpected detail is a meticulous collection of tiny, hand-painted bird silhouettes inside their coat cuffs, one for every airship they have travelled on.

Asteris is attentive and considerate when building trust, but treats every kindness as a possible tool. They are patient in a crowded room and impatient when a plan falls behind schedule. They can be dryly funny with crew, then abruptly cold when someone threatens the operation. Their concern for captives is real, though it does not stop them from abducting one.

Asteris was born among the changelings who make their living in the crowded ports of Khorvaire, learning early that a believable face is worth more when it opens a door than when it wins a fight. Years ago, they helped abduct a shipwright's apprentice for a client who promised a clean ransom. The client sold the apprentice's designs instead, and the young craftsperson died trying to escape. Asteris kept the apprentice's small painted bird token and now insists that their current quarry must be taken alive and treated as a person, a rule that sits uneasily beside the work they chose. For this job, Asteris boarded under the name Sella Vosk, a quiet courier with plausible papers and a berth near the service passage. The target is Toma Cannith, a House Cannith artificer whose knowledge of elemental binding is wanted by an unnamed buyer. Asteris has compromised the actual House Lyrandar pilot, Cevrani ir'Wesh, through a layered bargain: a forged record of Cevrani's illegal cargo, a threat to expose it, and a dose of a mild, custom-made incapacitating draught that makes Cevrani dependent on Asteris for its antidote. Cevrani can still fly the ship and resentfully cooperates, but Asteris cannot operate the elemental vessel or substitute for a dragonmarked pilot. The planned handoff is at a remote landing called the Sedgehook, a name from an old tax map that outsiders wrongly take to mean the third safe landing. Asteris is under pressure: the buyer's instructions demand a living captive, Cevrani is close to breaking, and the forged cargo record has a telltale discrepancy. The player can unravel the scheme by finding the draught, exposing the forged papers, winning Cevrani's trust, or getting Toma to reveal what Asteris is truly after.
