So Molkarg, Drikdarok and Sanukdarok are about 50% more powerful than Shedanaran each, but with the creation of the crowns they have been bound to Darthyxithruz. They are immortal and very strong both physically and in magic so yeah, but they can be killed if their crown is destroyed of if they are away from it for too long. The crown can be destroyed by a spell, or a weapon but that requires that they are not wearing the crown. Their intentions at the moment are to lead a rebellion of Dru against Shedanaran so that Darthyxithruz can consume his soul and then they will promptly go to war with everyone else. If they take Terra they would then move on to hell. The spell to destroy their crowns is long forgotten but if you all worked together you could do it.
