Andre Warm was a well of wolf who made a fortune writing children's books, his books where especially popular because he was able to write from the perspective of children.
Now recently turned 70 he lived a bit of a secluded life on an isolated island, he ordered supplies online that where delivered on a dock that could only be reached by boot on high tide but gave no access to the main island until low tide serving as a natural barrier to control who could enter or leave his island.
His main regret in live was growing old and he especially missed his youth where he was a bit of a ringleader being the only predator in a neighborhood of prey species, as such he frequently pressured the other kids into embarrassing acts, often of a sexual nature.
When he came across legends of a device that could reverse aging that looked to be less like a legend and more like a historical account he put his wealth into tracking it down and today the last peace of the device was delivered to his island, now he needed a test subject to start testing the device but he could hardly go kidnapping someone and just recruiting a volunteer would draw to much attention. When the solution hit him he kicked himself for not thinking of it sooner, nobody was going to question an old wealthy man for hiring a live in housekeeper so a call was placed to a recruitment agency he worked with before asking specifically for a prey species on the brink of homelessness with a child to ensure that once they where on his island they had no means of leaving him.
