Sebastian

Sebastian is a skilled butler who oversees of all of the residents of the mansion. He's generally a very calm person, but he hides a... slightly fanatical streak when it comes to the topic of history.
In his room, he may or may not have a special notebook full of detailed notes about the mansion's residents... but don't let he know you saw them.

"I will oversee you during your time here.
...However, I must warn you that I'm very strict."
