All servants belong to the castle, unless they are entering the castle with their Lord or Lady. Then those ones are personally owned. But if a servant is about and they have spent time getting to know the members of the room then and a Lord or Lady finds that they may possibly wish to own a servant then that Lord or Lady must approach Diamond or Winter to request such. It is also up to them to decide based on number of servants in the room if the request will be granted. Servants will NOT be given out willy nilly to Lords and Ladies we need to be sure we have enough servants to keep the home running smoothly and able to offer a serve as needed.
Also, no servant can be given to an outsider. They must be member of the home.
