If the sword of gryff is something that can be looted, the hocruxes can be something the scums have to assemble, too to summon or revive he-who-should-not-be-named or perhaps awaken a hidden ability one can have...

So there are 20+ death eaters in the story but I believe only 5 players to build the mafia: HIM, and either from the house of black and malfoy, and another heavy.
2 3rds maybe: one evil (dolores) and benign.
