The Order of the Grey

When Regulus discovers his "Lord" has made horcruxes, he realizes his loyalties are misplaced. James, Remus, and Sirius are dissatisfied with the Order. They hate how they only have to use stunner and second year spells or they are penalized. They hate that they are outmatched; and they hate that they are used as pawns in what Dumbledore considers his war.
