Percy Jackson and the Olympians: Legends

Agamethus's spirit appears as a typical Greek warrior, except that the head is cut off. He seems to be well-built with broad shoulders. He doesn't have a voice and he can't speak verbally. Agamethus wears a traditional Greek chiton tunic and sandals. He keeps a sheathed sword by his side. His tunic is stained orange, due to blood trickling from his severed neck. He has a ginger-colored aura around him. For some reason (choice or curse), Agamethus's spirit always appears like he was just before he died - his head cut off, his tunic covered with blood.

Agamethus, after his death, seems to have become wiser and more mature. He hasn't adopted an evil path. Rather, he has understood his misdeeds and repents for them. He has accepted his punishments with grace. He stays by his half-brother Trophonius, even though he has become the Dark Oracle. Agamethus has even forgiven Apollo for refusing to save his life at Hyrieus's treasury. Agamethus seems to have become more friendly and helpful as well. He brought little Georgina to the Waystation so that she could be safe there. He also became friends with Emmie, Josephine and the other residents of the Waystation.

Agamethus was the son of King Erginus and his wife. Trophonius was his maternal half-brother (his father was Apollo.) Agamethus and Trophonius grew up to become renowned architects. They even built Apollo's temple at Delphi. Agamethus's death (and Trophonius's downfall) came after King Hyrieus commissioned the brothers to build his treasury. They became greedy for Hyrieus's wealth. They built the treasury with a secret tunnel. They planned to slip into the treasury in the dead of night, steal the valuables and slip out via the tunnel. At the end of the book, after the Oracle of Trophonius had been blown up by Apollo, Apollo tells Agamethus that once he is a god again, he will try to get Agamethus a place in Elysium.
