So, I don't know if nonjon would allow this(<--PS: this is my round about way of asking if you would) but I just read The Caitiff's Death Eater Hufflepuff story which he says is largely inspired by your story. Anyway, I would love to see an AU where Harry is sorted into Hufflepuff and, although it doesn't have to be Dark!Harry, Hufflepuff house turns out to more or less follow nonjon's Hufflepuff Manifesto. It would be pretty easy to do in a one shot, but to be honest, it would be great if someone was even willing to flush it out into a full story. Provided of course nonjon is ok with this. Edit: I'm not actually making this a challenge yet since nonjon hasn't said anything, but if it turns out to be ok, I'll re-write this in proper challenge format.
