Tellah, known in the Japanese version of the game as Tella (テラ Tera?), was once the wisest sage in Mysidia and master of all spells. However, after a serious accident involving his magic, he retired to Kaipo, where he gave up sorcery and forgot most of his spells. He had a wife and daughter. When his wife passed away, and he learned of his daughter's secret engagement to Edward of Damcyan, he became furious. He left his home and traveled to Damcyan to confront Edward. Along the way, he meets and befriends Cecil and Rydia. Upon reaching Damcyan, he learns Anna, his daughter, has sacrificed her life to save Edward from Golbez. When Tellah learns how deeply Edward had cared for Anna, his anger towards him lessens and he vows to kill Golbez, leaving Cecil's group. During his quest, he realizes that his current powers are not enough to accomplish this goal, so he travels to Mt. Ordeals where his memories return and he regains his mastery over magic. He also learns the forbidden spell, Meteor. Rejoining Cecil to confront Golbez, Tellah casts Meteor. Doing so weakens Golbez, but it kills Tellah. In the final moments of his life, Tellah admits to Cecil that his thirst for vengeance had consumed him.

He briefly reappears as a spirit in The After Years, alongside Anna, advising Edward not to give up the fight against The Creator.

Tellah is voiced by Gorō Naya in Japanese and Lee Everest in English.
