Before Yoshitaka Amano drew the final artwork, Sabin, Edgar and their backstory were designed by Kaori Tanaka (later nicknamed Soraya Saga), an artist who would go on to participate in the development of Xenogears. Two royal siblings named Rene and Roni appear in the latter game. Soraya Saga also authored the doujinshi (a term for a fan made manga), Figaro no Kekkon: Tales from Desert, which explores Sabin and Edgar's backstory.
