Klug is a student of Primp Magic School that is known to be stuck up and rude, and is commonly perceived as a geek or nerd, or a "goody two shoes". He frequently carries a cursed book he rented from the Primp Town's library, and he continues to keep it through renewal.

His name is pronounced like the German word "Klug". Yet those other than Klug pronounce it "Kloog".
 

I recommend giving Klug a British accent.
