About that I have no idea.

I just remembered that Arcadios sucessfully blamed the kidnapping attempt in which the three idiots took off with Wendy and Porlyuscia on Raven Tail. I wonder if maybe Ivan did receive some kind of punishment for that, even though he wasn't the real culprint.

If so that might explain why Raven Tail was disbanded. It never made sense to me that the entire guild would first be banned from the GMG for a period of time only to be disbanded completely later. Not unless these two punishments were independant of each other.
