Who is Sister Imperator?

Sister Imperator is a character that only really appears in the web series, promotional videos, and a few music videos. She is portrayed as the sort of "behind the scenes mastermind" for the band, which is also a Clergy. She's is also Nihil's ex-lover! She has been there from the start, as evidenced in the music video for Dance Macabre and Kiss the Go-Goat. It's assumed that Dance Macbre is when she and Papa Nihil actually met, and it's implied they were already a couple during the Whiskey a Go-Go. Her first real life appearance was in 2015.

Sister Imperator also got into a horrible car accident once and they had to totally reconstruct her face, which definetly wasn't an in plot explanation for why they had to change her actress part of the way through. I'm not even sure if the woman in the profile sidebar is the right actress. God. Edit: she's not.

She also had Papa Emeritus I, II, and III assissinated to sell VIP tickets. So that's the kind of power she's got in her pocket I guess. Besides Nihil's balls. I'm pretty sure Cardi is her son, but uncertain if he's Nihil's son or not. Actually who raised any of these kids. This family tree is killing me. Edit: she is his mom and Nihil is his dad. Once again this family is a nightmare.

Sister Imperator tragically died when no one was looking after the concert in Rite Here Rite Now, because she refuses to let Cardi have nice things.
