The Serpentine Dukedom is one of the most influential families in the empire however it is also one of the most notorious, it was never neutral like the temple nor an ally to the empire. It was never intimidated by the imperial family instead it attacked the imperial family through false information. That sort of arrogance and confidence came from being established before the empire same as the others however they are just consistent and prideful. (The Serpentine family's power is like the Social media in our modern society, it can manipulate information from the highest to the lowest people of the society.) They are suspected of starting libel wrecking multiple noble's reputations and even hiding gambling, human trafficking and smuggling. They are also suspected of accepting bribery.
"Does the Serpentine family have an heir that is soon to wed?" Lady Lulu asked the brides of the emperor.
"Yes, Lady Luxsiel, they have" Lady Sa- rang said.
