Just a few points.
Grammar
faced extension (I think you mean extinction)
slained (Slew)
stucked (Stuck? Struck?)
totally destruction (Total destruction)
diminish evil (Eliminate, destroy, eradicate, vanquish or lift would make more sense)
prince of this town (I've never really heard of a prince of a town. Prince of a kingdom would make more sense)
Also you're either missing or misusing several punctuation marks.
Other than those errors, your story is pretty awesome. I must say that you put a good deal of thought into it, though I did noticed something. Fayt and Maria. I think those were the names of two main characters from Final Fantasy II, but whatever floats your boat.
You said that you can't post screenshots at the moment. Is it because your maps aren't fully constructed and you're working on events first? People would have a better idea on what to say about your game if they could see the work you've been doing.
Still right now, I'm liking this project. Just, if you can't on your own, get someone to proofread your test and dialogue just in case.
Hope to see some good results!
EDIT
One more thing. A good title for your game might be something like "The Chosen One"(Because the story is centered around that) or "Bridging the Divide"(Because the game's world is, in a way, divided in three) Just try and think of a nice sounding title that goes well with your game's story.
