History
On Earth-791218, Aged Genghis was one of the many mystics gathered by the Ancient One to deal with the growing threat of Dormammu's disciple Stephen Strange. When the idea of summoning Eternity was rejected, Genghis took note of Anthony Druid's suggestion to summon Eternity anyway. Genghis found a scroll that Druid mistook for a spell to summon Eternity, but in reality it would summon ultimate doom.
Later, when the Ancient One's and his followers created a barrier to protect themselves from an attack by Stephen Strange, Druid cast the spell despite the Ancient One's warnings. A portal opened and threatened to suck them through it to eternal doom. Strange and Genghis were both pulled through the portal, but only Strange survived the ordeal.[1]
