Sold in The Magic Shop as The Age Player's Spell Book but secretly was the cursed Age Vampire's Spell Book. On the surface the cursed book existed for those thirsting to return to times when they were younger or those seeking an urge to dominate someone into a younger state.
Each book contained spells to cater to the desires of those who sought the book. Spells inside could physically and mentally change whoever the target was. Spells could send one backwards or forward in time or even change their reality to match their desire. Even spells inside the book to help the spellcaster hide it in an emergency. Despite all this, these spells acted more like curses. The regressed were cursed to be dependent on others in various ways. Those that acted independent would find themelves in embarassing situations or facing further regression while unable to stop these moments. Some users even found the younger they were, they had made them almost uncontrollably horny all the time. The hidden curse of these spells is that the caregivers would soon act similar to age vampires.
Age vampires took the form of maternal figures, consuming the years off their victims for prolonged life and orgasmic pleasure. Originally the Spell Book was a means for continual power for age vampires to control the age of their victims. As much as age vampires enjoyed reducing their victims to infancy, they loved "seasoning" their victims with fear and humiliation. When the book was written, spells were created that would further alter reality as they saw fit to help this more. Despite the regressed being grown ups in their minds, they would be paralyzed to the toying that came from age vampires and many of the spells had this cursed side effect. Age Vampires loved mocking the pleasure the regressed had in their younger forms and sometimes acted as unskilled or forgetful mothers to leave the regressed in humiliating circumstances with their inability to care or clean for themselves. Human caretakers also took on these qualities that the age vampires had.
The book came with a warning that the regressed need a caregiver. Even a caregiver needed to be present to reverse a spell. An hour without one would find the regressed messing themselves and feeling themselves becoming younger unless a caregiver takes care of them. till they were the first few seconds of their newborn life with their bodies being swollen and sore. Without a caretaker nearby this summoned an age vampire who would then begin their own fun with the victims.
Some users, it was a fantasy fulfilled despite it's cursed limitations. For others, it could be a nightmare. These are the stories of some of their users
