I don't feel like wrapping spoilers over every detail so don't read if you haven't got to chapter 3.




Lenne wasn't from dream Zanarkand, she was a summoner from the real Zanarkand that was destroyed..Maechen must be an unsent then. Doesn't really make sense but that's really all it could be. However...didn't all the unsents vanish after FFX when Yu Yevon was defeated? If so then there must be some other way that Maechen knew Lenne and the connection Lenne has with Yuna and Tidus with Shuyin?
