Physical Description
:
Perrin is rather tall for his age (at 151 cm). He is rather tan, reflecting his mixed English, French and Chadian heritage (grandma maternal side). He had slightly wavy, light brown hair; dark green eyes, always underlined by faded dark circles.

Mental Description:

Perrin is a reserved but rather self-assured boy, more comfortable observing than participating in loud conversations. He isn't unfriendly, but he chooses his company carefully.
Academic success matters deeply to him, and he has little patience for people who make no effort to improve; people thus often describing hims as arrogant.
He has a particular fondness for books, logic puzzles, and shows early interest in Muggle subjects like mathematics thanks to his grandfather’s influence.

Biography:

Perrin was raised in a house with a small garden in Cambridge, not far from the city centre.

His mother, a potioneer, was strict but really affectionate.
Perrin’s strongest childhood bond was with his maternal grandparents. On this side of his family, his grandpa is recently retired Muggle botanist, who encouraged Perrin to attended a Muggle prep school, and to keep receiving tutoring in maths during the summer when his magical education began. His grandma was born and raised for the first years of her life in her mother's country, Chad, but they moved to England before she turned 11, as her French father had gotten a promotion and was happy about the idea of his daughter attending Hogwarts. Whenever she was alone with Perrin, she liked to tell him of her souvenirs of her mother's side magic, and of the beautiful landscapes of her country – which Perrin was lucky to visit the summer of his 10th birthday.

His father, a wizard lawyer, Ministry official in the law department, was often absent but constantly emphasized scholarly achievement and ambition.
Perris is a lot less acquainted with his family on his dad side of the family, but we can note that on that side his grandpa was a England wizard working as a layer, and his grandma also worked in law, who being French, had attended Beauxbatons.

First Instance of Magic:

The day before his sixth birthday, Perrin was in the garden while his grandfather (maternal side) tended to a tree. His grandfather, lost his balance of the ladder and began to fall. Without thinking, Perrin’s panic surged resulting in a patio cushion to fly a few meters and to position itself directly beneath him.
