wicked cool idea!!!
now...please don't hate me.
The first paragraph...nice opening sentence. The problem in the beginning, I think, is so much information in only three sentences. I had to go back and re-read it before I could put all the facts in order. Actually, as far as I could see, that was your main problem. You can be patient with your information....the most important (and this is perhaps totally wrong of me) information seems to be who Caleb is, what he does, and his contemplation of what is to come. The beginning, where you say "death is only the beggining" and talk about Bevon and Bualla and the War..this seems interesting, but you just suddenly drop it. If that information is really important, I would suggest either using it to lead into Caleb's contempation of the small town or take it out from the begging and indroduce it later at a time you can devote specifically to that.
Oh...should the tapestry be capitalized? I just noticed you capitalized the Weave, and then used tapestry to further explain the "greater currents and events".
Yeah....and what I said before: i think you should just be patient with your information. Don't rush to include everything as soon as possible. It can confuse, and sometimes even bore, the reader.
All in all though...I'm really curious as to what the actual story is about! Caleb seems like a cool character, and the whole idea seems neat.
I hope I helped a little...
Good Luck!!
