What an amazing story, with a great character introduction and detailed description and very impressive plot development, which makes this story very intriguing. You showed a great example of how character should be introduced in order to show their full power over his tiny subjects – the scale and the ease of transporting cities into the room just shows how insignificant these cities are compared to their ruler.
You are the author that always bring high quality content and I am sure that this story won’t be an exception. Really waiting for the next chapters with a hope that main character will come up with something interesting to punish these cities, which dared to disobey. ;)
