History
The mansion was directed by Roswaal A Mathers, later on several rooms were made, like a library where most of the knowledge of Echidna was saved, who created Beatrice to keep them safe. With the passage of time, the mansion came to belong to the margrave, Roswaal L Mathers, he hired Frederica Baumann as his maid, then he brought Ram and Rem, later he also took Emilia under his roof as his Book said so, she would only stay studying for the Royal Selection, to become the future queen. In order to keep his body in shape, Roswaal took the prana from Ram's horn every night. A couple of months before Emilia lost her insignia, Frederica stopped working at the mansion.

When Emilia brought Subaru as guest because he helped her with her lost insignia, he opted to work as a butler, helping the maids with the activities. Roswaal suspected Subaru, thinking that he was a spy, however, he went to attend some business. Sometimes Subaru visited Beatrice to ask her some things, until she discovered a shaman dog capable of making curses, so Subaru with the help of the maids managed to defeat him, at the last instant Roswaal reappeared, helping them to defeat the Wolgarms.

After a visit from Felix, and after having held a conference in the capital, Subaru stayed at the Karsten mansion. Rem decided to accompany him. Roswaal once again attended some affairs at the Sanctuary. Beatrice stayed longer in the library, Ram had to do double work due to the absence of her sister, so Emilia was completely alone. A few days later, Subaru returned with some merchants in order to evacuate all the people from the territory to the capital and the other half in sacred land, all to face the Witch Cult. Due to her contract, Beatrice remained in the mansion, on the other hand Ram called Frederica to take care of things in her absence.

Instantly there were a series of consequences, since Rem was erased from existence. When Subaru returned accompanied by Emilia and Otto, Frederica took care of them, she also hired Petra Leyte, who accompanied her in her work. A few days later, Subaru, Otto Suwen and Garfiel Tinsel returned from the Sanctuary to the mansion, where they confronted Elsa, as well as a few Demon Beasts controlled by Meili, unleashing a chaotic battle that little by little ruined the place even more. With Meili captured, the group left, not before Subaru made a new contract with Beatrice to leave the mansion, which ended up collapsing on top of Elsa.
