I apologize for being inactive for so long. I was sick and then attached to my 3DS when finally getting to a playthrough of FE: Awakening.

Anyway, a few things with the ending there. Considering his blindness, I'm wondering how he knew items only a psychic could know.
How was the chase unfair? This is more curiosity than anything else. 
How does he know they are "dark individuals"? I feel like vibrations from the earth wouldn't be able to discern whether or not someone's intentions are good or bad. I'm not sure how positivity and negativity can be transferred into the earth.
How does he know they're Kyoujin? Does he even know who or what they are (It's not supposed to be common knowledge as most people may have heard the term but know nothing about it)? How are they not just assassins or mercenaries or even law enforcement? Perhaps he had a run-in with them recently. Since they openly discriminate against Elementals but they haven't yet killed any, they've only been hired to take out governmental figures, or so has been reported.

These are more questions about the nature in which he sees (which I would assume is actually hearing and feeling). I don't want to needlessly inhibit your character but I feel like making him blind, even when Earthean, inhibits the character in itself. I can see him having a great sense of distance and also know how many people are walking and such, but what about jumping or "flying" (in the case of Akimoto's ability to use fire to fly) opponents?

I should have written this the day you posted (since that's when I read it)...but I'm a terrible person. >.<
