Now I read all the Potter books, and I still can’t name for you any important people that came out of Hufflepuff. To me, only two houses were ever fully developed, one a stereotype for ‘good’ the other for ‘bad’. Ravenclaw came a distant 3rd, as there were a couple of characters you got to meet from there.
Overall though the houses were in very, very broad strokes.
Having said that, Nantaris would totally go Ravenclaw. I always liked them best.
