Mender is one of the best Auror's in the business. For 5 years he was part of an exchange program in which he worked with the UK's top team: Hermione and Harry Potter.

With them he was able to foil an attempt to stir up the goblins by unknown parties in 2010, and has been declared Goblin friend by the Crushed Stone tribe.

He appears to be a great admire of Mr Gray who has taken strong steps to reduce the power of dark creatures and dark wizards within the US.
