The synopsis leaves much to be desired. The exposition at the start of the first chapter feels a little too long but it's bearable.

It likely would be more hooking if the start is a flashback of some sorts to a battle. An extra tidbit here: some descriptions of an object's external features feel half-done as I couldn't imagine it clearly
