Zarin Sand is a recurring character in the fifth and sixth seasons, though he was alluded to in Season 4. Zarin is the bastard son of Prince Oberyn Martell and his paramour, Ellaria Sand. Although not a Sand Snake himself, Zarin has vowed to exact revenge on those who killed his father. As far as anyone knows, Zarin is the only bastard son of Prince Oberyn.
Adventurous, lustful, and charismatic, Zarin has a dry, sarcastic, and dark sense of humour combined with a quick wit and barbed tongue. He is a capable fighter and uses nothing more than a small knife when fighting enemies.
