An enigma among The Oathsworn, Alweard's boyish appearance belies a steely, hardened gaze only earned through years spent in a constant state of war. Nonetheless, he keeps his past close to his chest. A perpetual spinner of tales, he has a tendency to share extravagant stories about curses in the Dwimordene, adventures on the sea, writing a book under a Gondorian name, and other implausible exploits rather than reveal any verifiable claims about his past. 

This much is known: Alweard has been rumored to have sworn no oaths to Lord Thorvall, riding with his present company as a liaison for Théodred out of Helm's Deep. While his voice is soft, his spear-arm is quick; he steps swiftly and silently and smiles regardless of whether he is a welcome guest or an unwelcome nuisance. As a man of letters, he has been considered eccentric among the Eorlingas, but he claims that his literacy is of great use to any man of the Mark who would be his friend. Having spent time in Gondor on a diplomatic mission in his youth, he speaks multiple languages, but shows his skills little until they are needed. More recently, he has volunteered to keep records for his warband, recording the distribution of treasure and funds in the Oathsworn's stronghold of Fylstott.

Despite his current affiliations, he claims no lord save for the Second Marshal; if the rumors are true, he has spent long years as a strategist and scout in his commander's service. His old companions have known him to vanish from the battlefield for weeks or even months at a time, always on assignment. Since he was first seen riding alone, he has named neither father nor hometown that would indicate his origins, although his manners may provide a clue. Any past honors or glories he might have are not the subjects of any songs save his own.
