Guys, relax... I doubt Avatar was meant to be a powerful enemy... and I really think it's too eraly to see it as an enemy. This is a rag-tag group of wizards, half of which may not actually be Zeref worshippers but just pretending to be black wizards so they could bait Zeref to reveal himself. I still think that this is a dummy guild. Sure, maybe some members are Zeref worshippers... but it is implied that most of them have no idea as to the origins of their fellow members. They don't have files on each other... except for Gray (as for now). It's a manufactured "guild" that has a vague ideal or concept as to why it was created in the first place. I don;t see any real "leader figure" in that group, and most of them are in the dark as to what they are supposed to do, or what would happen, or on what should happen. The "for Zeref!" battlecry is very general, and at best it may have only been used to grab the attention of the Council.

Then again, I might be wrong altogether... and Mashima may just have gone full Kishimoto and turned Fairy Tail into Naruto... God help us all if that happens...
