This wasn't Qin Shi Huang? Oh. That's the one I had in mind as well

"Almost correct" you said? Hmmm... I have 2 possible names but none would qualify for Sabers (unless Imperial Privilege has something to do with it, like Nero) : Li Si, for his bureaucratic methods leading to a better administrative unification of China, and Zhao Gao for his manipulative actions (and because the idiom attached to him is worthy of being a Noble Phantasm, although I don't see the effects of the one displayed here fitting the bill)
