Iona

Iona, also known as the White Dragon is one of the pieces of the Tempest Dragon created by the Goddess Altea, and the only fragment that remained untainted by the Void Dragon. She retains most of the memories of Tempest, although some are less clear than others, likely due to Tempest's mind and body fragmenting.

Trivia

 * Iona doesn't possess his own lustre, and, as such, refers to himself as a ghost.
