Quartigod youngest son of the demigod Nestor of Pylos by an unregistered mother (Anaxibia daughter of Cratieus in Apollod. 1.9.9, or Eurydice daughter of Clymenus in Hom. Od. 3.451-452); tier = (0.5 + 0)/2 = 0.25. The courteous young prince of Pylos who first welcomes Telemachus, becomes his close companion, and drives him by chariot to Sparta and back in the Telemachy — and weeps at Menelaus's table for his brother Antilochus dead at Troy. He survives (no death/transformation attested), so NO lifecycle is authored; vitalStatus deceased reflects his eventual mortal end. Brothers Antilochus and Thrasymedes wired reciprocally in-batch; the mother is unregistered so only the father edge is set.
