Kaldor Dorn is a wiry male gnome with iron-gray hair gathered into a precise topknot and a neatly trimmed pointed beard held by three tiny brass rings. He dresses in immaculate dark leather, polished boots, and a high-collared travel coat lined with hidden pockets. His hands are always clean, his fingernails carefully filed, and his voice is soft, rapid, and pleasantly conversational. Within a minute of meeting him, most people notice that he rarely blinks while listening, and that his breath becomes unnervingly quiet whenever he is calculating a threat.

Kaldor is charming, observant, and relentlessly pragmatic. He treats every conversation as a negotiation and every room as a puzzle. He can be genuinely generous, especially toward displaced people and clever inventors, but his generosity often creates obligations he intends to collect later. He is fascinated by systems of power and quietly believes that morality is mostly a luxury enjoyed by people who already feel safe.

Kaldor was born in Brambleglass, a secluded gnome settlement whose homes were concealed beneath living roots and illusion-woven stone. His people prized clever devices, quiet agreements, and the certainty that any problem could be solved with patience and the right tool. Kaldor learned early that locks had personalities, guards had routines, and every secret eventually revealed the shape of the person protecting it. He became the settlement's unofficial finder of misplaced things, then its unofficial taker of things that belonged to people who had too much of them. When a greenskin warband found Brambleglass, the settlement was destroyed in a single night of fire, iron, and screaming. Kaldor survived by hiding inside a maintenance shaft beneath the old clockworks, listening as the homes above him collapsed. He emerged to find no family, no community, and no one left to punish the killers. Since then, grief has curdled into ambition. He joined criminal networks, learned how to move through cities unseen, and began collecting favors, blackmail, coin, and weapons. Kaldor no longer wants merely to avenge Brambleglass. He wants enough power to make the destruction of another settlement impossible, or to become the sort of tyrant no army would dare challenge.
