Berek's black hair reaches the middle of his back, its coarse lengths brushed upright at the front to sharpen a pronounced widow's peak. His face is narrow and intent, with soot often caught in the creases beside his nose. Four iron studs line each eyebrow; two more sit at the front of his chin, while three small iron bolts cross the bridge of his nose from side to side. Rows of iron piercings run along both forearms from elbow to wrist. He is lean through the waist but corded across his shoulders and back. He stands with his weight settled over the balls of his feet, as if listening for a hammer's rebound, and his breath catches in tiny measured pauses when he is thinking. The unexpected detail is that he keeps a tiny, carefully tended pot of blue alpine flowers on the hottest shelf of his forge, shielding it from sparks with a little copper hood.

Berek is patient with metal and impatient with excuses. In the forge he is exacting and quietly generous, offering fair prices and teaching anyone who shows care. Outside it he is wary, dryly funny, and reluctant to let anyone see how much he worries. He dislikes being praised for courage, yet will step between danger and a stranger before considering the cost.

Berek learned the forge from his mother, who made hinges and farm tools in the riverside town of Sava. At seventeen, he joined a caravan smith crew and discovered that his gift was not merely making metal strong, but noticing what it would become under strain. During a winter siege, he was ordered to repair the gate chains while trapped townsfolk pounded from the other side. His commander demanded that he finish the weapons first. Berek instead sabotaged the commander's blade and used the recovered metal to reinforce the gate; the delay cost the garrison its position, but saved the trapped families. He left the company in disgrace and has since built a modest forge near a busy road. He sends part of each season's earnings to his mother, though he has not visited in three years. His former commander, Doman, now buys weapons from local smiths and has begun asking pointed questions about Berek's past. Meanwhile, Berek's apprentice, Ildiko, wants to turn the forge into a place where anyone can learn the trade, a plan Berek fears will attract the wrong kind of attention.
