Theory: Maybe the Former Magic council Chairman is one of the 4 Gods of Ishgar.. Maybe them excluding Walrod Cken, holds the organic link to the weapon "Face".. And Face is probably an ancient weapon of the Magic Council probably a 100 years ago.. That's why the present members of the Council probably don't know anything as well as the members from Michello's time in the council.

So, maybe a back-story of how the Magic council was formed may be shown, and then a back-story how the guild Fairy tail was founded..
