After a re-read, I picked up on a few more things that I missed the first time and some things that sank in more.
Quin was remade, with out the controlling device that Liron had made here with, but also without her wings.
Unless I missed where they were re-attached... She needs her wings, not blue or black, but here original color(s).
Illya... oh, Illya how you really messed up again and yet again when given 20,000 years to fix your error. I will be interested to see if he can get his shit together and be worthy of Corrine's/ Zaria's love. Illya's choice in warning the twins, still doesn't sit well with me and seems out of character. He had so many options if he didn't want to see them murdered by Wylend. Also, if the Mighty wanted the future to be changed by Illya, why not just command him to do what they wanted...
Wylend... wow.
I am guessing that Warlend and Wellend were forbidden from interfering with Wylend's rule so that the time line wouldn't be altered. I'm guessing that the small not about Wellend allowing his brother to rule in his stead was what allowed Wylend to sit on the throne without dying and then later Ry could sit when Wylend abdicated.
Timelines/time travel/the RD drug.... I really hate when I think about these things. the whole Zaria being Welland's Daughter and the ring coming to her 20000 years in a past that she didn't exist until Bree put her there. If Bree hadn't done this where would the Ring have gone?
Basically, how can the RD drug's usage affect the past? isn't it supposed to evolve the recipient to a future self? Or I'm I not understanding the drug's effects. if this is how it works it should only have affected the future. Wylend may sure that Zaria wouldn't be born (20000 years in the past), so this should have never been a future life to be evolved to.
Another scary thought.... exactly what did Cayetes evolve into? Quin should know. what ever it is must have mind speech and sent for V'ili, how else would V'ili have known to show up at that exact moment? so many questions.
I know I am reaching, trying to apply a little logic and some accepted time travel theories here.
