Loprin Manor

This is known as the "mistress house" where ancestors to the MC kept their unofficial lovers. Located in an out of the way place in Len and accessible by back roads only, about 30 minutes away from the main manor.

It's luxurious, and maintained by paid servants and Zhenzhen. Roulan the pet also lives there.

It's a mansion with a beautiful garden, a large pond with a water pavilion, where Zhenzhen could often be found swimming in the nude, and a very secure underground dungeon complex with strong magecraft inhibitors for prisoners.

At the start of the game, the Loprin Manor is guarded by a lightly-mind controlled commoner hero who in turn controls a half dozen undead thralls as guards. Dou Rong is the prisoner. Zhenzhen/Roulan has no idea about the presence of Dou Rong, the commoner hero who commands the guards, or the guards as there is a separate entrance to the dungeon complex aside from the houses.
