This is not a reincarnation or transmigration story.
There will be no cheats like systems, wishes etc.
There will be no cliche situations where he finds an ancient inheritance on the road or becomes the prince's heir etc
Everything that Severus gets will be due to his intelligence and hard work.
I don't know if he will be a villain, but I can tell he won't be a goody two shoes like all might.
And, finally, Severus doesn't have Sauron powers.
It will be his new name like Voldemort for tom riddle.
The love interest is fixed.
No harem, but multiple flings between Severus and other female characters.
I will add more info if required, for now that's it.
