X's Backstory:
As a child, he left his family to find a place to claim as his home. One stormy night, he stumbled across a fenced garden. X has not adjusted to the modern culture (literally living in a cave) believing someone imprisoned a bunch of wildflowers. He squeezed under the gate and made a flowering shrub his home. Unbeknownst to him, the garden belonged to Aster's family, with the flowers actually being herbs. They discovered him one day eating an apple falling from a tree, and when they went to confront him, he hurried back into his many hiding places.
The cycle kept on repeating until the witch family noticed that his presence was keeping the pests away from their valuable herbs, so they let him stay. Even going as far as to bake him apple pies and other treats using their apples. Aster and Amyntas became childhood friends, much to Amyn's annoyance, but they went their separate ways when they grew interested in other things.
