Physical Description: Rudolf is a fairly thin, relatively tall person, standing at about four feet and ten inches. He has heterochromia, with one eye being green and the other being blue. He has very pale, almost translucent skin, providing a significant contrast to his jet black hair. He is rather attractive, but does not flaunt his looks.

Mental Description: Rudolf is shy, timid, gentle, kind, and incredibly, incredibly smart. Coming from a pureblood family, he learned a lot about magic before being able to come to Hogwarts. Despite his shyness and timid nature, he has a big heart and cares deeply for those he knows well. He is book-smart, but he also shows a great affinity for practical work and problem-solving. His ambition is significant, hoping to become either a Magical Researcher or an Auror.

Biography: Born and growing up in a fairly rich but strict Slytherin-Ravenclaw pureblood family in Oxford, England, Rudolf received a comprehensive education from a series of governesses throughout his childhood before Hogwarts. He was educated in the ways of mathematics, literature, music, history, and logic, though he did not receive an education in muggle-related studies due to his pureblood family. His mother and father were relatively strict, but they still cared for him and loved him dearly. Rudolf grew up as an only child, which made him feel rather lonely. He longed to make friends, but it was difficult for him to do so because of how shy he was. His parents believed that sending him to school would help him break out of his shell.

First Instance of Magic: Rudolf first displayed an instance of magic at a very young age, around the age of 4, in the Rosen family manor in Oxford, during a mathematics and logic class from his governess. He displayed minute telekinetic powers as the sticks being used to display unit values began to shuffle on the table without anyone touching them.
