I was looking through some stuff on hp-lexicon when I stumbled onto a familiar sounding character:
I later realised the character sounded familiar because he had the same last name as the main "antagonist"/puppet Percival Graves.
He is listed in the piece as one of MACUSA's Original twelve Aurors.
The descendents of the original twelve aurors have a special place in American wizarding society; Graves's family is still influential in American wizarding politics today.
Is our friendly chappy Gondulphus related to Percival and hence why he's so beloved? Or are their last names just a coincidence?
