This is Zeb Gulch, younger brother of Zamira. He’s 25 years old, Slytherin class of 1971, and employee in the Beasts Division of the Department for the Regulation and Control of Magical Creatures.
He’s a halfblood and a purist (I know) who believes in wizarding supremacy in the magical world. He deals in criminal creature smuggling. He likes smoking, drinking, and wearing leather jackets with his combat boots. He comes across as very devil may care and is defensive of his background if challenged because at least he has magical heritage (unlike some people tyvm). He hangs around Jamie Goyle and his lot so there’s that as well.
