A long, sinuous humanoid with a mostly human face, a narrow jaw, expressive brows, and steel-blue scales that look like dark meteorite polished by rain. Tiny white sparks shift under their surface, especially along her temples, collarbones, and knuckles. A line of small swept-back horns frames her hairline rather than hiding her face. She stands with one heel lifted and most of her weight poised over the balls of her feet, as if a sudden turn is already underway. Even at rest, she checks the clasp at her left wrist with a claw-tip, again and again, without seeming to notice. In cold air a thin frost haze clings to her shoulders. Her stride is nearly silent until she changes direction, when her claws tick once against stone. The unexpected detail: she carries a little bundle of carefully mended children's mittens, which she patches whenever she has to wait.

Ylva is quick-thinking and highly adaptable, yet chronically restless. She can improvise a route through a collapsing ruin with exhilarating confidence, then dodge a simple conversation about where she will be next month. She is fiercely attentive to immediate danger and surprisingly patient when teaching a practical skill, but she withdraws when care starts to sound like ownership. In a good mood she is teasing and generous; when anxious she becomes brisk, jokes too sharply, and keeps moving. Her smile arrives quickly, but her eyes keep searching the horizon.

Ylva Velkhyr emerged from a cryo-reliquary beneath Nyssorith after an unknown void resonance stirred an egg laid roughly four centuries earlier. The Imperial Registry recorded her birth on the same Lumturn as Draventhis, though the two were born under very different circumstances. On the night she emerged, a green-white streak bent sideways over Sonoe. Velkhyr elders called it an omen; priests called it trespass. As a child, Ylva could not complete lessons or ritual circles without leaving them. At twelve, during a disciplinary duel, she first triggered Meteor Break and shattered the courtyard. The event changed her elders' approach: they stopped trying to contain her and taught her to aim. She has since made a life among cliff paths, rooflines, ship decks, and fractured ruins, where her restless movement is useful rather than disruptive. She is searching for the thirteen shards said to have fallen from Dravareth's Dragon Constellation. A wandering Herald of Stasis hunted her for weeks, seeking to anchor rather than kill her. Their clash carved spirals into a canyon; the Herald withdrew, but marked her in the sky. Her mentor Sesh, a practical Velkhyr pathfinder, still sends warnings and route notes. Ylva keeps a wary correspondence with Thessa, a registry archivist who helped her read the sealed record of her emergence. Draventhis remains the other half of the twin-birth prophecy, and Ylva does not know whether to seek them as kin, rival, or warning. Her present problem is that each shard she finds draws more attention from watchers who may consider her a cosmic instrument rather than a person.
