Helenus found the city of Buthrotum. After Neoptolemus left Epirus, he left Andromache and their sons in Helenus's care. Neoptolemus was killed by Orestes, Agamemmon's son, in dispute over Hermione, the daughter of Menelaus and Helen, whom Orestes had been promised as wife, but whom Neoptolemus had taken. As the kingdom of Neoptolemus was partitioned, this led to Helenus acquiring the rule of Buthrotum, as king. "Helenus, a son of Priam, was king over these Greek cities of Epirus, having succeeded to the throne and bed of Neoptolemus." Andromache bore him a son, Cestrinus, who is identified with Genger or Zenter,
Neoptolemus by captive Andromache, daughter of Ēëtion. But after he heard that Hermione his betrothed had been given to Orestes in marriage, he went to Lacedaemon and demanded her from Menelaus. Menelaus did not wish to go back on his word, and took Hermione from Orestes and gave her to Neoptolemus. Orestes, thus insulted, slew Neoptolemus as he was sacrificing to Delphi, and recovered Hermione. The bones of Neoptolemus were scattered through the land of Ambracia, which is in the district of Epirus. Although Neoptolemus is often depicted thus, the play "Philoctetes" by Sophocles shows him being a much kinder man,
