Grimarr Ironhide is a broad-shouldered mountain dwarf with a weathered face, iron-gray beard, and dark brown eyes that rarely leave the nearest exit or the nearest threat. His beard is braided in the old Ironhide military fashion and bound with dull steel rings. A faded scar crosses his left cheek, while a second, deeper scar runs beneath his ribs from the Breaking. He wears practical travel leathers beneath a battered mail shirt, carries a heavy shield marked with the Ironhide oath-circle, and keeps his father's medallion close to his heart. His equipment is maintained with almost ritual precision, though every piece bears the scars of long service.

Grimarr is stern, patient, and deeply protective. He speaks plainly, keeps his promises, and prefers practical solutions to grand speeches. Beneath his military reserve is a dry, unexpectedly gentle sense of humor, usually directed at his own stubbornness. He has little patience for cruelty, cowardice disguised as pragmatism, or commanders who treat common soldiers as expendable pieces.

Grimarr Ironhide was born into the Ironhide clan of Kazâd-Khur, the Hammer-Heart, a fortress carved into the Greyreach Mountains of Telluris Res. His father, Borrin, served as garrison master-at-arms, while his mother, Helga, was a retired watchwoman whose discipline was sharper than any blade. At twelve, Grimarr received his first handaxe and his father's most important lesson: an oath has no beginning and no end. Break it, and you break yourself. He carried those words into the Greyreach Pikemen at twenty-seven, where Sergeant Thrain Stonebrow tempered his temper into battlefield sense. Grimarr learned to fight not merely as a brawler, but as a shield for those standing behind him. During the Siege of the Amber Pass in 305, a Gurzun warband ambushed a refugee convoy of three hundred souls. Grimarr and twelve soldiers held the flank for two hours against overwhelming odds, buying enough time for the civilians to escape. For that stand, he received the Iron Band, Kazâd-Khur's highest military honour, and was promoted to captain of Westgate Garrison. He never believed he deserved either distinction. In 309, a routine patrol became a trap when forty soldiers found themselves surrounded by five hundred Gurzun warriors. Grimarr refused the offered surrender, led a savage breakout, and won the battle, but nineteen of his soldiers died. He resigned soon afterward, unable to accept that victory could feel so much like failure. For two years he wandered the lowlands of Rivenmarch as a caravan guard and mercenary. An encounter with an aging half-elf ranger named Marek taught him that the weight he carried was not only a burden. It could also be fuel. Now Grimarr travels in search of a purpose he can keep without breaking himself. He carries his father's unbroken oath medallion, a Gurzun tusk taken at Amber Pass, and bone dice won from a trader. He still fears the day another command will demand more lives than he can bear, but when danger comes, he is always the first to plant his feet and the last to retreat.
