Hi! In this post, we shall discuss about the ugly old hag from FE6, Niime! First of all, her background. Niime is the mother of Canas from FE7, and the grandmother of Hugh from FE6.

Yodel: Yes... Indeed.
Niime: ...Now, I think I understand how you felt that time.
Yodel: Yes... I too understand your argument.
Niime: But that was a long time ago...it's a time that's gone forever. Our paths split on that day. They'll never cross again...
Yodel: ......
