Marvel Two-in-One... Presents The Thing And Iron Man (vol 1) #12 VF

Ben is out in the Israel desert, where he's test-piloting something called "Pattycake" for Tony Stark. The launch goes awry, however, and instead of being lauched into the air Pattycake (with Ben inside) is propelled deep into the earth. Ben crawls out of the wreckage, and unexpectedly finds himself in a cavern. Seeing a light at one end, he heads for it...      Meanwhile, Tony Stark has suited up as Iron Man, and has figured out what must have happened. Heading into the silo, he find the ruined ship, but no Ben. Looking around, he finds Prester John, and Ben kneeling as if in supplication before him. PJ holds a magic stone out in front of Iron Man and Iron Man finds himself forced to kneel before Prester John, and has to listen through the story of PJ's earlier appearance and history. Prester John then strides off to conquer the world, leaving Iron Man and The Thing immobilized behind him...
