I second the previous commenter, but perhaps you should have not ended it there. Anyone not familiar with the source material would wonder "what happens next?" If you would have gone just a bit further, and ended it right before Alm and Celica go to face Duma, that would have been better. Include Jedah in shock that his witch was restored and storming away to Duma's altar.
I love it when people offer to read my stuff, whee! I don't think this is too long...

PM me your thoughts. Xenoblade, but...an AU, and quite the tweaked one too.
