This is where I don't get the Emperor, he's boasting about his trash piece of ass and showing her off, even holding parties for her and stuff. That's just beyond reality, no wonder the nobles are snidely laughing, he's a fool (and a cuckhold).
He's the disgrace ..... What more it's not even his child. Previous empreror will investigate every women background first before continuing them as their lover. But this guy, he even shows off her. Like
There are level with being a concubine as well, with the Empress supposed to be in control. This happened in both Eastern and Western empires. It's surprising that someone like an Emperor would be taken in by this girl, but I guess that's the author's leeway - they seem to spend a lot of time on establishing these idiots as Navier's enemies.
A mistress or concubine who doesn't have a background baby will never become a prince or princess. Only those imperial concubines baby can.

What more an ex-slave who just popped out nowhere
