A lean half-elf man with warm brown skin, dark auburn hair worn close at the sides, and a narrow braid tucked behind one ear. His pointed ears are modestly sized, and his amber-brown eyes rarely settle on a person's face for long. He moves with a quiet, asymmetrical gait, favoring his left side as though always making room for an unseen companion. His fingers repeatedly check the position of the leather cord around his right wrist, a habit that becomes more obvious when he is lying.

Mahir is courteous, observant, and almost unnervingly patient. He remembers small vulnerabilities, such as who limps, who drinks too quickly, and who looks toward the door when a certain name is spoken. He dislikes shouting and prefers making people feel that they have reached his desired conclusion on their own.

Mahir Dastan was born between two worlds and learned early that belonging was a luxury other people could afford. His human mother kept accounts for a caravan house, while his elven father served as a guide through wooded borderlands. When the caravan house collapsed under debts and accusations of theft, Mahir discovered that ledgers could be more dangerous than blades. He began altering manifests, hiding contraband in legitimate shipments, and selling route information to whichever buyer paid first. His talent for reading tracks made him especially useful when stolen goods had to cross country without attracting attention. A failed exchange left Mahir with a choice between prison and the service of a local criminal network. He chose the network, then quietly arranged for the guards who knew his name to receive false evidence against one another. Since then, he has worked as a smuggler, scout, and occasional bounty hunter. He became a ranger not from reverence for nature, but because wilderness provides better hiding places than cities and because a patient hunter can make a death look like an accident. Mahir now travels with adventurers when their goals overlap with his own, treating every friendship as an investment and every trail as a ledger of debts.
