Eoleo

Eoleo is the son of Briggs and Chaucha from Champa. On several occasions he is seen using Psynergy which leads the party to think he is an Adept. It is assumed that Eoleo used his Psynergy power to free Briggs from the Alhafra prison which allowed Briggs and his crew to escape to steal the ship.

It is revealed through Chaucha that Eoleo obtained his powers when he was struck by a falling stone, most likely a Psynergy Stone.

Eoleo's Psynergy
There has been a lot of speculation about Eoleo's Psynergy. Since neither of his parents, as well as no one else in Champa (except perhaps his great grandmother), display any ability, so many theories have been forwarded.

Ankohl
Some people think that he is directly descended from the Ankohl who built the ruins to the north, unlike the rest of the Champans, who presumably have lost their ancestor's talents or have lost the purity of their blood. Considering the Ankohl's apparent ability to forge metal and the themes of the puzzles in the ruins, that would make him an Venus Adept. This is the most accepted theory.
