Scion-tier (1/8 divine through Theseus → Poseidon-line) son of Acamas by Laodice daughter of Priam — the only Theseid-line continuation attested in primary sources, and the only attested cross-line union producing offspring between the Theseid (Athenian-Poseidonian) and Priamid (Trojan) royal houses. Conceived during Acamas's pre-war embassy to Troy; raised in Troy by his grandmother Aethra during the war; recovered by Acamas at the fall of Troy; killed by snakebite while hunting in Thrace during the return-voyage. The death terminates the Theseid-line continuation.
