You were born into royalty in the kingdom of Poketopia, a medieval and modern civilization filled with people and Pokemon. as a baby you had to be separated from your family because of an evil entity is after you, then you were left in the care of a hermit in the woods who was a family friend.

Many years later you are now a 15 year old with your own pokemon(you can choose any), you heard rumors about a lost princess/prince from all over the kingdom.
