I don't mean to completely ruin it, but.
Acmed, you wanted dragons and that isn't Dragons. Sure I could tie it into something, but it's not really floatin' my boat. Good for a intro for a character, but not first chapter.
I'll agree to the small-ish word opening for each main character and how they get to the castle, etc.
Also, peasant, warrior, and prince? Yes, way too cliche. We totes have to have a female present ^-^
I'm all for a warrior, but I don't think a prince belongs. Peasant is meh-ish. But I'd rather have some other lowly person than a plain peasant.
Backtracking to Chillz shizz, your opening doesn't have a medieval ring to it, except for the armor.
Anyways. If we only have a select amount of writers, please don't write about yourself. You're trying to write in a third-person type thing. So don't infuse your persona into a character completely. Sure, give them a few traits but not exactly like you, because you'll have to write for multiple people.
This is beginning to resemble all of the other AG stories, where you enter and you actually write for yourself. That's just how I see it with having so many writers. I'm also starting to see just how unorganized this really is... good thing this is the back stage, because if this was official it would have no hope of making an impact.
