Nice intro of Mission and Zaalbar and you have a bit of mystery with the missing arm. As to posting chapters and such, one of the many suggestions is to employ a beta reader who would be able to stop any spelling, grammar or things that just don't seem right. Often a fresh pair of eyes can pick up things you don't at first.
One thing that really has me hanging on is what is the mysterious secret that has the Exile wondering how Mical knows. Keep it up.
