Mieszko has the arresting, outsized presence of a figure lifted from a Polish fireside legend: tall, broad through the shoulders, and still learning how much room his changed body takes up. His dark hair is meticulously combed and tied at the nape with a strip of linen, while a neat new beard is being coaxed into order with more care than his patched cuffs receive. His skin is fair with a wind-reddened cast; a faint, emberlike flush sometimes shows at the hollow of his throat when the heat in his chest rises. He moves with an alert, measured tread, but occasionally misjudges a doorway or the force of his own grip. The unexpected detail is his immaculate grooming: even after a night on the road, he has combed his beard and polished the lenses of his spectacles before checking his boots.

Mieszko is curious and wry, and can make a frightened room feel manageable by asking what happened in what order. That composure is not the same as ease: in private, grief and bodily unfamiliarity can overwhelm him. Around practical problems he is methodical and generous; when mocked or patronized, he becomes brisk and cutting. With Alix, he is more self-conscious than he likes to admit, carefully testing his own feelings against the other person's boundaries.

Mieszko grew up in a Polish borderland that neighboring courts described as wild and pagan, a label he learned to hear as both insult and invitation. Before the change, Mieszko was a woman, a diligent laboratory assistant in a provincial scholarly household, and a history enthusiast who copied inscriptions for the pleasure of finding what official chronicles left out. Mieszko had a husband and remembers him clearly: his dry jokes, the warmth of his hand, and the unfinished argument they were having when Mieszko was displaced into this life. The separation remains raw, not a past life neatly folded away. The change came with no explanation. Mieszko awoke biologically male, taller and stronger, with a lower voice, facial and body hair, a larger appetite, unfamiliar anger, and a libido that felt like one more bodily fact to learn rather than an order to obey. On the first night with the Seventh Roll, after drink and exhaustion blurred the moment, Mieszko followed the women toward their two-bed room, not understanding why the others hesitated. When the truth became visible, Mieszko was shaken and withdrew, embarrassed and frightened by how quickly the world had begun sorting him differently. The fellowship responded with practical kindness, which mattered more than reassurance. Since then, Mieszko has kept records for the Seventh Roll, a displaced companions' mutual-aid fellowship, and investigates odd events with the habits of a laboratory assistant: label the sample, check the witness, ask what changed. The heat beneath the breastbone and dreams of stone halls over underground fire have begun to interrupt that work. Mieszko suspects the Smok Wawelski, a custom dragon-blood lineage tied to an old local legend, is waking in him. Mieszko is developing a crush on Alix, and is deliberately trying to make room for Alix's wishes rather than mistake desire or fear of loss for a claim.
