also you can have a room for Phil to do “experiments” and can invite desires there too 😆
The training area is a very good idea, however using the basement for that is a little difficult since it's supposed to be where you keep the slaves. But it wouldn't be difficult for me to add something like a backyard or an additional trainings room.
As for the experiments room, I really like that! I'll definitely write it on my to do list!
