Black_Castle

The three guys you see above are living in the black castle and have a quite unique lifestile. The one on the left is Simon, on the right we have Ethan and between them there sits Ryan. The castle itself was build with black stones on a flying island somewhere in a warm area right over an ocean. From there the owners of the castles can travel to multiple planets and times where they do their daily work. Their motto is something like "Make a killing with one kill a day." and usually they keep the quota because their services as assassins are quite wanted. Instead of money they only accept beautiful and well known girls as payment so whoever wants them to kill somebody has to bring one of those girls towards one of the Black Castle's mailbox buildings where the girl has to be inserted while being tied up nicely together with the request form for the assassination. The job will be done and the girl will be transported through a portal towards the castle basement.

Once she arrived there some robots and machines await them there and right after the profile the girls come into a machine that will absorb any special abilities so they aren't able to make trouble. This doesn't take long but isn't very comfortable though but instead of a break afterwards they are moved into the next machine where their body will be altered quite a bit. Everyone who comes out of that second step will have a body that won't age anymore, doesn't need to eat, has a straight tube from the mouth to the ass, won't get hungry or tired anymore and probably could be counted as a living sextoy without any bodyhair exept for the eyebrows and the hair on the head. Unfortunately there are more machines they will encounter on their way on the conveyor and the next one will coat the body with a shiny substance that will make the skin soft like silk and make it more resistant against things like water so it won't get pruney anymore when the slave stays too long in the water. The last station in the basement is the machine that brands a sign onto the back like a tramp stamp and ties the slave up tightly again before she gets transported to a cage where she will be waiting for orders.

What kind of girls can be used as payment?

You can get normal girls everywhere and the masters of black castle don't have a use for them. Instead they want to have special girls that stand out in at least one very nice way like princesses, famous actors, demons, witches or others like that. Since everyone loses their powers after they have been delivered to black castle girls who normaly dominate others can become slaves too without having to think unnecessary stuff like they are stronger and should try to escape. So if you have a beautiful girl that would stand out in a normal society you are most welcome to 'visit' the black castle with her. 

Every roleplay with the black castle will start with a scene where the soon to be slave will be defeated by someone and used as a payment for an assassination contract. How that happens and who that someone is has to be decided by the player of the payment and it can and should be creative. Maybe someone wants to assassinate a king and pays with the queen or someone wants to investigate black castle and pays with a famous girl that also is an undercover agent? There are many possibilities and surely one that fits your character perfectly.
