AU in which the royal magic is gifted to retainers through a magical sex ritual. A lot less porny than the description makes it seem. More of a coming of age angst fest that delves into the meaning of consent and free choices.

Every royal is given Retainers. These Retainers are expected to attend to your every need, even the ones behind closed doors. This is a story examining Prince Noct's relationship with his three Retainers, told in segments and timeskips across several chapters.
