Heidi was a bit of a crazy girl at Hogwarts. She had the reputation for getting around. She played really hard on the field and usually found a nice girl to blow off steam with. ;)
She is very driven and desperately wants to be a team leader (and possibly team captain one day!)
She has some demons and a lot of baggage from the war so she usually puts up a strong front but there are deeper things for those that can crack her hard shell!
