Argus has the narrow, soft-cheeked face of a child who has not slept well, and a habit of leaning his weight toward the nearest exit. He keeps his injured little finger wrapped against his palm, the bandage faintly smelling of clean linen and sharp spirits. When he moves, he takes quick, uneven steps, then stops so abruptly his coat hem swings past him. His unexpected detail is the small, careful way he tends a sprig of common mint tucked in his pocket, rubbing its leaves between thumb and forefinger when panic loosens its grip.

Argus is watchful and frightened with strangers, yet warm and physically affectionate with family. He wants to be brave enough to help Kaitlyn, but terror often freezes him before he can act. Once calm, he is observant and curious about small things, especially plants and familiar household sounds.

Argus was raised at the Buckland family manor alongside his older sister, Kaitlyn, in rooms where polished wood smelled of beeswax and every ancestor seemed to watch from a painted frame. A recent ordeal left him and Kaitlyn trapped in the family crypt. When the adventurers found them, Argus cried, shrank away, wet himself, and refused to leave. During the rescue, the party's dog bit off his little finger. Someone assured him it would grow back and threw something at him; the words and gesture have lodged in his mind more firmly than the explanation. The party later recovered the finger. Argus remained terrified as they escorted the siblings toward Buckland Commons, where he ran to embrace his uncle. His uncle took him to the manor to rest, but the crypt's darkness, the injury, and the strange promise about regrowth remain unresolved in his thoughts.
