Sargon maintained contacts with several other mages in the DC Universe, notably Baron Winters, Zatara (a fellow "faux" stage magician), and the younger mage John Constantine. Sargon answered the summons of Constantine to participate in a ritual at the mansion of Winters to help deal with the effects of the "Crisis on Infinite Earths", using the Swamp Thing as their portal into the war being fought in Hell. Locking hands in a circle of power, and using the psychic powers of Constantine's drunken acquaintance Mento, the group of sorcerers (which also included Zatara's daughter Zatanna) observed the events unfolding, and attempted in turn to channel their magical powers into several other mystical characters present in Hell, including Etrigan, the original Doctor Fate, and the Spectre.
