Valerius stands with the rigidity of an iron pike. His skin is the color of storm-lashed granite, mapped with a network of fine white scars that trace the history of a hundred skirmishes. His movement is deceptively slow and deliberate, suggesting the weight of mountain stone. He has heavy, calloused hands that never seem to shake. Paradoxically, despite his rugged, mud-stained exterior and the constant smell of ozone from the wall wards, he maintains a meticulously groomed mustache and smells faintly of imported lavender oil, a small luxury that reminds him of his wife's garden before the wars.

Valerius is a study in stoicism, appearing cold and mechanical to the recruits he commands, yet he harbors a frantic, burning anxiety for the valley's safety. He is famously generous with the common soldiers, often paying for their medical care out of his own coin, but he treats the Joerin nobility with a biting, barely-veiled contempt. He is a man of absolute duty who nonetheless believes that sometimes the law must be broken to preserve the spirit of the kingdom.

Born in a mining camp beneath the Twin Titans, Valerius was the sole survivor of a collapse that unsealed a forgotten pocket of the Underdark. He watched his father pulled into the shadows by creatures with too many limbs. He joined the Iron Legion to ensure no one else would face those horrors. Years of service on the Great Wall taught him that while the Endless Desert is a visible threat, the true rot is rising from beneath. He recently executed a secret order to wall off several royal mining shafts, an act that has put him at odds with the Crown's treasury but saved dozens of miners from nameless terrors.
