So Magic changes, Magnus has some kind of conniption fit and changes how it works. (Great cover for the change of the magic system in the next game or DLC)
Now the Synod, A greybeard, the College of Whispers, Psijic Order, some Underground group of Necromancers and the College of Winterhold decide a pow wow is in order and the Arch-Mages of the respective organizations decide that bringing one or two assistants to the super secret neutral ground meeting place (New area for DLC) is all anyone needs. So if your the Arch Mage, then you pick a helper or two or the Arch Mage picks his second in command and you and the Augur of Dunlain tags along, this is also a cool chance to have all the major mages in the game (Court mages, and the like) in the same area (College courtyard, asking for answers).
Then instead of blaming eachother, being sensible men of magic they realize working together is best. Though squabbles happen. Eventually it's figured out that to 'fix' magic we will need to basically absorb Magnus. Leading us to a big boost in magical attributes or pouring his essence into a weapon, making it very OP.
Any thoughts?
