Dormammu imprisons Clea, and tells her she will witness Strange's defeat. Mordo tells Dormammu that Strange is searching for "Eternity", and cannot understand why this upsets the dark lord so. Strange continues his search, going from one practitioner of the arts to another without result, until The Aged Ghenghis tells him only he and The Ancient One know the secret. He gives him a scroll, which leads Strange to a being imprisoned in another dimension, which he barely escapes. Back in Tibet, Strange tells his master's servant the only option left is to enter the mind of his master...; Desperate to learn the secret of "Eternity", Dr. Strange probes into the unconscious mind of The Ancient One, meeting one deadly trap after another, until at last, he reaches the mind of his beloved Master, and convinces him of his identity and good intentions. After recovering, Strange departs, and high atop a Himalayan peak, recites "one of the most potent spells of all time". When he's finished, his amulet floats into the air, expands in size, and a doorway opens-- thru which Strange steps. Seconds after the amulet vanishes, Mordo appears, just barely too late to catch up with his enemy.
