I'd like to join but I have some things to do before I can make a bio, I'll edit this post in a few hours.

EDITED

Name: Klaude Siegfried Nein.
Nicknames:Siegfried, Sieg;He hates the name Klaude because of the obvious pun when you leave out his middle name(Cloud nine) and so he uses his middle name instead, Siegfried,usuallu only teachers call him Klaude.

Year:6th.
Wand:oak, 14'', Dragon heartsting.
House:Slytherin.
Personality:You can tell he's a from a long line of Pureblooded wizards, he's horribly arrogant and shares those ideas that only purebloods are worthy of learning magic and such.
He's a smart kid but the Nein family habit of marrying their cousins has left it's mark on the family, there's a history of mental ilnesses in his family and Sieg himself suffers from Obsessive Compulsive Disorder (OCD), though he is good at keeping it under control, it still interferes sometimes with his personal life.
Appearance:
History:He grew up despising mudbloods and blood traitors, and this only intensified after his father was killed by German Aurors(Back then he and his family still lived in Germany.) and the rest of his family were thrown into jair when their roles in anti-muggle crimes could be proven.

Only Siegfried wasn't arrested since he was only 7 at the time, he was the only child born in the family for years(It has been theorised that is a result of the cousins that have been marying within the family) and was taken in by friends of the family that lived in england.
