You have sired a childe. As the sire, you are definitely in control of the relationship. But as with other allies, they will come to you with favors as well. You do not have direct control of them as with Retainers, but you can expect them to work toward goals that you set, within their limited skill set. (This is a proposed merit in need of discussion. It could provide incentive to Cams, certainly, to work for favors from the Prince (or, if no Prince, their immediate elders) to get permission to sire childer. Could have some advantage over Retainers and Allies.
