Elrich is a tall, broad-shouldered aasimar with warm bronze skin, close-cropped black hair, and calm silver-gray eyes that seem brighter in dim light. His build is sturdy rather than imposing, shaped by years of marching, carrying equipment, and standing watch. His hands are heavily callused across the palms and fingers, with neatly trimmed nails and a habitual grip that makes every object look like a tool meant for practical work. Before speaking, he takes a quiet breath through his nose and briefly presses his tongue against his upper teeth, as if making certain that his words are properly ordered. He wears well-maintained chain mail beneath a plain military tabard, carries a spear and several javelins, and keeps a small wooden gaming set tucked into his belt pouch.

Elrich is patient, observant, and unfailingly formal with strangers. He speaks in short, deliberate sentences and prefers useful questions to dramatic declarations. He is gentle with frightened people, respectful toward honest enemies, and noticeably more comfortable repairing equipment than discussing his own feelings. His sense of humor is dry and often arrives several seconds after everyone else has stopped talking.

Elrich was raised on the edge of a fortified border town, where his celestial heritage was treated less as a blessing than as another responsibility assigned to the family. His first clear memory is of standing beneath the town gate while an old sergeant taught him how to keep his feet planted during a storm. The lesson stayed with him. He joined the army young, not because he dreamed of glory, but because the walls needed guards and the frightened needed someone who would remain at his post. His quiet discipline and refusal to abandon civilians earned him a modest rank, though his unusual lineage made some commanders expect miracles from him that he could not perform. During a disastrous retreat, Elrich carried wounded soldiers from a burning supply yard while the rest of his unit withdrew. A pale radiance gathered around his hands as he closed one dying scout's wounds, and the experience left him convinced that divine gifts are obligations, not proof of superiority. He eventually left formal service after refusing an order that would have sacrificed a village to protect military stores. Now he travels as a paladin, seeking causes where law and mercy can stand together. He still thinks like a soldier, measuring exits, counting supplies, and watching the horizon, but his oath is to protect people before banners, commanders, or convenient orders.
