Velius is a slim, rather tall boy who has very dense shoulder long brown hair as well as sharp greyish blue eyes. He has very distinct eyebrows as well as lashes. This gives him a curious, intrigued but firm look.

He is seen as sociable and fun to have around, although he can be sometimes very stubborn and eccentric, when he wants something, which potentially pushes people away. Velius is very dedicated and enthusiastic about his interests, he is very perceptive and can be quite creative, this on the other hands attracts people to him.

Velius' parents met by accident, his father being a Ministry of Magic official sent to a Muggle hospital to reverse a magical accident, where his mother, a Muggle nurse, was working at the time. They live in a medium-sized English town, their surrounding is mostly made up of Muggles, which forces them to hide their abilities to a reasonable degree, but they also have some magical friends as well.

Velius first instance of performing magic was when he was five and in his Muggle Kindergarten during a stage play he and his peers had to take part in with all the parents watching. He got stage fright and felt so embarrassed that the room filled with a thick smoke that hid him completely. He was so busy with remembering his lines that he didn't notice though and just continued acting. But the parents freaked out and the Muggle fire brigade was called.
