@Aro Sure!
Well, basically I tried to give a name/title to the villain of our plot but ended up getting help creating a more solid plot. As you may know, in the TP timeline Twinrova never dies but Ganon is banished to the Twilight Realm. Well, in the meantime he had many daughters, one of whom has proven herself to be a very strong Gerudo. Ganon, for our purposes, dies in the Twilight Realm at the hand of Midna and her people who over-powered him. Thus, the triforce of power went to Twinrova who decides to try and train Ganon's strongest daughter in the ways of their dark black magic. Now, she leads a resistant force against Queen Zelda who had a hand in trapping her father. She is known as the Moon Mother because she is believed to be the mother of the next Gerudo King, or so it has been foretold by the elders of the tribe. Those that work for her are known as the Eyes of the Moon and do their deeds in the shadows. No one from the Eyes of the Moon has been seen and neither as the Moon Mother.
She still needs a name, but ye. That'd be abouts it.
I tell you this stuff because I figure Xander must have some idea of what happening. Though, if you'd like he could be completely as in the dark about it as Derae is and learn with her from his own mother when they finally do get to the castle.
