I enjoyed reading this story. Great take on a coup of a government, by someone breaking through the mind-control which happens. I have marked several spelling errors. If you do not use the American language as your first language I know some of my markings are not correct, so please check at your end. The correction program I use to help me is Grammarly which is set to AP standards. It does not like the Oxford rules.

I have included a line-by-line review below:
Red- corrections needed
Blue - suggestive corrections and remarks

***Frad wondered how many times he had heard those words. It had become a ritual, a routine so well practised (spelling) that every step was automatic.
*** Frad targeted the settlement and fired a mini missile. (hyphenated)
***They even shared the unusual black and white markings on his head that he thought made him unique. (opening quotes) Was this where I was taken from? (closing quotes, possibly put this in italics) he wondered.
***“For me,” said Ordan, “It (lowercase on -i) has to be the Palace of Joy.”
***“What's the point in a pleasure moon when you don't feel pleasure any more.” (one word) He waved his metallic arms as if to demonstrate.
***We can go together – me, Ordan (comma) and Mina - unless she changes her mind again.” They all laughed.
***“The Dark Fleet is a noble organisation, (spelling) with centuries of legend behind us.
***“They do marvellous (spelling) work, don't they. (question mark not a period) Every now and then one of our crew suffers a lapse such as you have.
***“It is likely that you are heading for an early retirement.
***Frad turned to leave the room, but as he approached the door a doubt came into his mind. He paused and half-turned back to the Commander, and he spotted him signalling (spelling) to the door guards, who in turn reached for their guns. It was clear they meant to kill him.
***The Dark Fleet is a murderous organisation (spelling) of brainwashed killers.
