Scaled Down Scales
a Kalashtar Battlemind, "twin" sister of Li Sun
Originally a paladin with an inferiority complex, Sun Li was convinced she could neither heal well nor play the role of defender well. All she knew of her mysterious origins was that she was raised in Celestia.
Obanar, the Last Guardian of Argent, did something to clear up this confusion when he revealed that she was actually something of a genetic freak, embodying ALL the genetic material of BOTH her father and her mother. (Apparently the Celestians took her from her parents because they have some kind of prophecy about such a diploid individual being some kind of savior.)
