(Taken from the Mages Guild page: "Vanus Galerion, a Psijic of Artaeum and student of the famed Iachesis, began organizing users of magic from around Summerset Isle at the urban city of Firsthold. [...]

Galerion was brought before Iachesis and the King of Firsthold, Rilis XII, and made to state the intentions of the fraternity he was forming. Although it's not recorded what he said to convince them, the charter was approved, and the Mages Guild was born."

It was founded in 2E 230. Nah, I'm afraid that won't be possible
