Eldrin is a narrow, silver-skinned human with a scholar's stoop, long fingers, and the careful movements of someone carrying invisible glass. His black hair has gone white in two distinct streaks above his temples, as though moonlight touched only those places. Fine ink stains climb from his fingertips to his wrists, and his left cheek bears a shallow scar shaped like a crescent. He walks with a carved ash cane, though he rarely needs it. His clothing is immaculate from a distance, but close inspection reveals singed hems, repaired seams, and tiny handwritten notes sewn inside the cuffs. He leaves an impression of fragile precision until danger comes near, when his posture straightens and his stillness becomes unnervingly predatory.
