Avengers #225

« The Fall of Avalon »: Dr. Druid appears at an Avengers meeting and transports all but Iron Man, whom his magic cannot affect, to 12th century Avalon, where they find their former teammate, the Black Knight. Amergin, the wizard-ruler of Avalon and Dr. Druid’s ancestor, explains that the extradimensional isle is the last line of defense between Earth and the realm of the monstrous Fomor. The Fomor attack, and the Avengers defeat them by switching opponents. In retaliation, Cethlann summons her husband Balor, whose single eye emits a beam that makes Thor and the She-Hulk vanish. In the confusion, the precognitive Bres invades Amergin’s tower and uses the summoning spell to transport himself to the present.
