Trophonius was the son of Apollo and King Erginus's wife. Agamethus was his maternal half-brother (his father was Erginus). Trophonius and Agamethus grew up to become renowned architects, and built Apollo's temple at Delphi.
Agamethus's death (and Trophonius's downfall) came after King Hyrieus entrusted to the brothers the task of designing his treasury. They became greedy for Hyrieus's wealth, and designed the treasury with a secret thieves' tunnel. They planned to slip into the treasury in the dead of night, steal the valuables and slip out via the tunnel.
Unfortunately for them, Hyrieus had inspected every nook and corner of the treasury and discovered the secret tunnel. He had set up a rope-activated crossbow trap to catch any thief, intending to find out who planned to rob him.
When the brothers came out of the tunnel with the treasure, Trophonius sprung the trap without realizing it. As a result, Agamethus got trapped in the tunnel, crushed under a beam. Trophonius was unable to pull his brother out. Agamethus then decided to sacrifice his life, and told his brother to cut his head off and then run away. This way, Trophonius would be saved and Hyrieus would be unable to discover the identity of the thieves. Trophonius pleaded to his father to let him die instead, but Apollo, disappointed that he had chosen to use his talents to become a thief, ignored his prayer. He was forced to decapitate Agamethus before running away.
Miserable and guilt-ridden, Trophonius wandered the earth for months before he was turned into the Dark Oracle.
After Commodus's captives are rescued, Emmie and Josephine try to put their adoptive daughter Georgina onto the Throne of Memory to extract her prophecy and cure her madness, but she refuses to sit until Apollo comes back. Once he is present, she speaks, but rather than a prophecy, it is a message addressed to Apollo, telling him to come with Meg to his cave the next morning. He also calls Georgina his "little sister", implying that she may be a child of Apollo.
When Meg and Apollo arrive at the cave, Meg begins to pour her feelings out in the cave, attempting to keep hundreds of water snakes at bay. This allows Trophonius to give her the prophecy, and he mocks Apollo.
When Apollo and Meg leave the cave, the spirit of Trophonius asks Apollo to blow up the oracle, because he doesn't want to be used by Commodus anymore.
