Gulnar is a broad-shouldered mountain dwarf with a square, weathered face, iron-gray eyes, and a thick russet beard braided with small brass rings. His beard is trimmed to keep it clear of his shield and sword, though one stubborn braid hangs over his left shoulder. He wears polished chain mail beneath a blue-and-silver tabard bearing his noble house emblem, and his shield is engraved with a rising sun over a dwarven fortress.

Gulnar is formal, disciplined, and intensely dependable. He speaks plainly, dislikes wasteful displays of emotion, and believes promises should be treated as binding contracts. Beneath his stern exterior is a protective, patient man who quietly repairs damaged gear, remembers the names of servants, and always takes the least comfortable watch.

Gulnar Brawnhorn was born into a respected dwarf noble house whose ancestral halls guarded a vital mountain pass. From childhood, he was taught that rank was not merely a privilege, but a contract. His family collected taxes, settled disputes, maintained the fortress walls, and answered personally whenever the pass was threatened. Gulnar proved more comfortable in armor than at banquets, yet he learned the ceremonies of nobility well enough to speak with authority in a council chamber and command obedience on a battlefield. When a raiding host breached the pass through a neglected drainage tunnel, Gulnar discovered that several officials had taken bribes to ignore the repairs. His own cousin was among the conspirators. Gulnar exposed the betrayal, but the scandal damaged his family's standing and left him convinced that laws are only as strong as the people willing to enforce them. He swore the Oath of Devotion before the shrine of the dwarf sun god, pledging to protect the innocent, uphold honorable order, and never allow family loyalty to outweigh justice. Now he travels as a paladin, seeking threats to dwarven settlements and testing whether his strict principles can survive a world where good intentions often conflict with lawful duty.
