This is a nice and funny story and I hope you continue it.

Would it be possible for Kaepora Gaebora to be Naesala, somehow I think it fits.

Very good so far. It ran smoothly and was pretty funny throughout. I don't have any Fire Emblem games except the one for DS with Marth in it (can't even remember the name; that's sad), so it's interesting learning about Tibarn.
