I love it when people who hold power are used as puppets. It makes for very powerful plot twists in literature. There are a few areas of improvement that I could point out though.

1st) don't be afraid to be descriptive. If you have an expansive vocabulary, use it.
2nd) Try to make it flow a little more, it was a tad bit choppy.
3rd) you didn't describe key elements such as the keep in very much detail. It is almost as if it just appeared out of no where.

Now for the good point...

1st) Very original names, and creatures. This shows creativity and potential for great literary pieces.
2nd) Excellent use of the human (or in this case wolf) flaw of hubris. Hubris is one of the most underused traits in my opinion, and it is good to see someone besides myself use it ^_^
3rd) Your use of allusions is also quite good. It could be further developed in a longer piece, but for this piece's length it is well presented.

Overall I like the whole idea of the plot, but I would like to see it in greater detail. Not bad at all for your first piece though. Alot more advanced than the first attempts of many people I know.

thanks! more description, more of a flow, goddit

if you really like this i'm more than willing make a longer more in depth version
