Vaelen is a lean human man with the compact balance of someone accustomed to moving across narrow gantries above molten rock. He takes up less space than his reputation suggests, standing slightly sideways in every room as though already measuring an escape route. His soot-stained traveling cloak hangs from one shoulder and has been repaired with careful red and copper thread, while the lining bears hundreds of tiny stitched marks that form a private map of Aethelgard's buried passages. His hands are broad-palmed and heavily callused, with blackened nails that never quite lose the smell of metal polish. His hair is cut close at the sides and curls tightly over his crown, dusted gray at the temples despite his age. The unexpected contradiction is his immaculate cipher ring, a small iron band polished until it shines like still water, which he touches with almost ceremonial tenderness whenever someone speaks of family. He moves with a quiet, catlike economy, but when he laughs he throws his head back and fills the room with an unguarded, startling warmth.
