Durin is a compact, broad-shouldered dwarf with a dense black beard braided into three squared-off cords and iron-gray eyebrows that nearly meet over his nose. He stands with his weight evenly planted, heels slightly apart, as if waiting for an inspection or the first impact of a shield wall. His voice is normally a low, measured rumble, but when rattled his breathing becomes sharply audible through his nose and every word arrives clipped and precise. He wears well-maintained chain mail beneath a soot-darkened tabard marked with a simple white anvil.

Durin is disciplined, patient, and quietly protective. He speaks sparingly but remembers every promise, route, name, and warning given to him. He prefers practical kindness to compliments, repairing a strap, standing watch, or placing himself between a companion and danger. Around campfires, he unexpectedly enjoys dry jokes and competitive dice games, though he insists that luck is merely poor planning wearing a disguise.

Durin Meltstone was raised in a forge district where every family kept a hammer, a ledger, and a story about the mountain. His clan worked iron and basalt, shaping tools for miners and anchors for fortress gates. Durin was never the strongest apprentice or the sharpest planner, but he possessed an unshakable instinct for standing where he was needed. During a tunnel collapse, he held a failing support brace in place long enough for six miners to escape. The brace broke, the mine was lost, and Durin was found buried beneath powdered stone, still gripping the iron pin that had kept the passage open. That act earned him a place in the local garrison. As a soldier, Durin became a dependable shield-line fighter and a strict believer in orders that protect ordinary people rather than merely impress commanders. He carries a greatsword that once belonged to a fallen sergeant, though he treats it less like a trophy and more like an unfinished duty. He now travels beyond the mountain to find the source of unnatural tremors threatening the roads and settlements below. Durin believes every disaster begins with someone ignoring a warning, and he intends to make sure no warning goes unheard again.
