I think its both silver and white maiden. For one thing a person of fame can have many nic names to glorify or to seem larger than life. Also they may have one nic name and other people (not famous) may use many variations of the same name hence silver and white. I dont know how many people on this site follow the NBA but Shaquille O'Neal has many many nic names and mentioning any one of those (Shaq,the big cactus, superman, the big aristotle, the diesel) everyone knows who your talking about. In this instance I believe Chris is refered as the silver maiden by fellow Zexens and possibly other "humans" (non-tribal) and the non humans like the lizards and the tribal groups like the Kayarans refer to her as the white maiden, maybe due to skin tone.
