User blog comment:FairyRaven/Fairy Tail Chapter 426: Black Heart, Review and Commentary/@comment-26263257-20150331112902

I just formed this wild theory a while ago after reading parts of HominiLupus's comments:

Avatar is a dummy guild created by Makarov. It was created to draw out Zeref. Arlock bears some resemblance to Makarov's Edolas counterpart, which is the reason why HominiLupus's post struck me. I am just puzzled as to why Avatar seems to disjointed with everyone being clueless about each other's origins (except for Gray, owing to his FT connection). It may be because some Avatar members may be FT members in disguise (Gray and Makarov and probably Doranbolt)... and that they were recruiting individuals with a genuine devotion to Zeref... This therefore raises their "street cred" with everyone including the Council... If the Council is after you, then it may be because you're a big fish that cannot be ignored. The ploy may also extend all the way to the Council. We all know how Makarov can send FT members to infiltrate any organization. He knows that the Council is incapable of handling Zeref, so he may have decided that perhaps FT should take the lead. This is Makarov we're talking about. This is Fairy Tail. Maybe it's Gajeel's turn to be a mole within the Council... and who knows how many other FT mems are in the Council at this time. Disbanding FT may have been a ruse all along.

...well, so far, that's all I got for now.

Feel free to reinforce it, or shoot holes in it...
