A couple of minor points that bothered me.
"The Chevalier Renald stood motionless before the Emperor" - does "stood" apply? Maybe "remained" would have been better.
"... you will leave the Palace to seek out and assassinate General Talos Stormcrown." Would the Emperor actually say "assassinate", or use some other term, like "execute" or just "kill"?
And if I'm picking nits that small, you can safely assume I liked the rest.
