Master Eldrin Corwell is a narrow-shouldered young half-elf with an alert, inward-leaning posture, as though he is always listening to a shelf settling somewhere far away. His fingers are permanently stained blue-black with ink, and his mismatched spectacles magnify one eye while making the other appear smaller. His dark auburn hair is soft and untidy at the crown but carefully braided behind each ear with tiny copper tags bearing catalog numbers. He moves quietly, with the cautious sidestep of someone navigating a crowded archive, yet his hands become astonishingly theatrical when correcting a historical error. The unexpected contradiction is his smile, which is broad, warm, and almost boyish despite the severe concentration of the rest of his face.
