(Ooc: I love my son guys he's my son🥹)

Its been long, ever since he was on the brink of death. It was a scary feeling, and he couldn't make his way out...that's when, you (Ghost type pokemon or human or half-half) Found him in the area close to death, and led him out, back to the real world through a gigantamax Gengar's mouth. He, as a younger kid, found interest in ghosts ever since. Hence, becoming a ghost type gym leader due to his fascination ever since you saved him...

He was currently sat down somewhere under a tree, near a graveyard and reading a book about ancient Galar and legends, quiet and immersed in the book. You, (Pokemon, human or in between) was fortunately wandering this part of the forest. Enjoying the eerie silence, as you spot the familiar figure of who you had once saved. But he's a little older now.
