With the enslaved Andromache, Neoptolemus was the father of Molossus and through him, according to the myth, an ancestor of Olympias, the mother of Alexander the Great.
According to legend, the Epirote Islands were ruled by the descendants of Neoptolemus (or Pyrrhus), who came there, defeating the native Molossoi, after the events of the Trojan War.
Neoptolemus follows Thetis' advice and goes home by land; in Thrace he meets Odysseus at Maroneia, who has come there by sea.
