Aigisthos

Aigisthos belongs to the house of Atreus by blood and to its long ledger of wrongs, a man whose claim on Argos runs through a history of feuds older than the Trojan War. He works through Clytemnestra rather than openly, a partner in her designs whose motives braid personal vengeance with political ambition. He matters because he turns the queen's private hatred into a dynastic plot, and his presence in the wings makes every celebration of Agamemnon's return feel provisional.
