I don't think actually any reader is going to see this, but I'm writing it anyway. Since if there actually is one that stumbles upon my promotion, he should be a very picky reader with particular genre in mind.
Well, if what you seek is the truly evil, the clean depravity and malice, then my book might be the one you're searching for.

I know of two popular novels based on history and the like, however I have not read them so see for yourself.
One is 'Commonwealth' and the other is called 'Revival of byzantium'.
I think I have found something on royal road. You might want to try and take a look there.

Custom*
I am not sure, yet I have already seen someone doing it in a famous novel called 'Custum made demon king'.
I think the book 'shapeshifter parasite' might be to your liking then, if you haven't read it yet. At least in my opinion.
(It is not mine)
Mine it has 'obviously' no romance, however i know it isn't for everyone, as the MC is quite evil.
You might give it a shot if you want.

Totally free, would appreciate your opinion about it.

You could try mine if you want, as I assure you that it was no harem or romance, since the species of the mc is rather 'peculiar'. However i might warn you about heavy elements of violence and gore.
Lastly its a sci-fi fantasy type of story.
