Elgo

Elgo is mysterious figure who briefly accompanied the Warriors of Light.

Story
Elgo meets Sol's group in the Northern Cave: they are on their way to the Temple of the Crystal when they see Elgo fighting a monster. After helping out Elgo, he tells the party that he was also on his way to the Temple of the Crystal because he sensed a "disturbance" regarding the Crystal. After arriving at the Temple and entering its Chamber, a mysterious being shatters the Crystal as the group of Nacht, Sarah, and the twins Alba and Dusk arrive.

After the explosion, finding Sol, Aigis, Dusk, and Sarah separated from their respective groups, Elgo tells them they were chosen by the Crystal to become the legendary "Warriors of Light", and decides to join them on their journey. After taking over a Warship, Baugauven, one of the Avalonian Empire's generals, appears and overwhelms the Warriors of Light with his Heatwave. When Baugauven unleashes his Final Backdraft to finish them off, Elgo sacrifices himself to take the deathblow meant for the others. After Baugauven falls back when the Warship is suddenly attacked by dragons, Elgo then tells the party that he was sent to serve the Warriors of Light before handling the airship's steering wheel to crash it somewhere where the damage could not do harm while the Warriors of Light escape.
