History
On Earth-791218, a world where Stephen Strange was a disciple of Dormammu, the Ancient One and a number of gathered mystics would briefly consider summoning him, but deciding that it was too dangerous. When Strange battled the mystics for the first time, he found himself shunted to Eternity's realm. There, he was confronted and attacked Eternity. Finding Strange a paltry foe, Eternity sent him away.
Later, Strange seemingly slew the mystics with the Eye of Agamotto and attempted to use it against Eternity. This was the master plan of Dormammu who would use Strange as a conduit of his power to try and destroy Eternity. This plot failed as Stephen was, after almost being driven mad, chose the side of good and was returned to Earth by Eternity.
The Eternity of this universe, as well as its alternate reality counterparts, was annihilated by the Beyonders.[1] But were likely restored alongside the rest of the multiverse.[2]
