Elrond is a tall, lean wood elf with long ash-brown hair bound with strips of faded military cloth. His hands are unusually distinctive, broad-palmed and heavily callused from years of sword drills, shield work, and maintaining campaign equipment. He wears chain mail beneath a weather-stained cloak and keeps his shield close even when at rest. Within a minute of meeting someone, it becomes clear that his attention rarely stays on the speaker. His eyes travel constantly to exits, weapons, hands, and possible points of advantage. His expression is controlled, almost courteous, but his stillness has the watchful quality of a predator waiting for movement.

Elrond is soft-spoken, observant, and unsettlingly patient. He is unfailingly polite to people who can be useful and theatrically courteous to people he intends to undermine. He enjoys military anecdotes, not for their heroism, but for the small failures that caused them. He prefers practical conversations and becomes visibly amused when others appeal to fairness, honor, or tradition.

Elrond served for decades in an elven border company that guarded ancient woodland roads from raiders, monsters, and rival clans. He was not renowned for discipline, but for results. He learned to read a battlefield as other elves read weather, noticing where fear would spread, where a commander was bluffing, and which sentry would abandon a post first. His superiors tolerated his cruelty because his plans worked, until he began arranging skirmishes for personal amusement and treating captured enemies as pieces in experiments about obedience. When his company finally discovered that Elrond had sacrificed an allied patrol to lure an enemy warband into a more favorable position, he was stripped of rank and cast out rather than executed. He kept the insignia anyway, wearing it inside his coat as a private joke. Now he travels as a mercenary, adventurer, and occasional instigator of violence. He is drawn to causes with strong loyalties because loyalty gives him something valuable to corrupt. Beneath his polished manners is a simple conviction, that every group can be broken if its members are made to fear one another more than they fear him.
