Liona is the third Alterran transformed by the Repository of Knowledge. She comes from Destra, and was once part of the anti-Ori underground
In truth, Liona is the former ascended Lantean known as Morgan Le Fay. She retook physical form as a means to hide from the Ascended Empire after the battle in Destra. Her face and body have changed, due to the Repository's changes as well as a few auxilliary ones to further hide her former identity.
