|First Appearance||"Final Dreamer"|
Eidon met Tony Jones after witnessing the battle against Korg and Zet. Eidon gave Tony a Translator Bracelet to allow the two to communicate. Eidon then brought Tony to the nearby town of Vash Naroom, introducing Tony to the village elder, Orwin.
Despite Orwin's warning, Eidon took Tony to the Naroomese training grounds. The two were caught by Orwin following the earthquake due to the appearance of a Shadow Geyser.
Following Tony's success at the Shadow Geyser, Eidon returns Orwin, who had been poisoned by the Shadow Geyser, to Gia's hut. Eidon then remained there and helped to carry out chores.
He also helped Tony by constructing a pair of Crystal Gloves to dig a path to the Underneath. Eidon later witnessed Tony's capture by Morag following Tony's return from the Underneath. However, Eidon was restrained by Zet and was not able to intervene.
After returning to Vash Naroom, Eidon took part in celebrating the defeat of Agram. If Orwin was not healed by Tony, Eidon would become the new elder following Orwin's funeral.
