In the 13th century, when Satan showed Yigael visions of the future Antichrist, Damien Thorn, Yigael went mad and painted images of Damien and his origins onto the wall of a chamber in Tel Megiddo. That wall then became known as Yigael's Wall.
Carl Bugenhagen discovered Yigael's Wall in the ruins of Megiddo. When Bugenhagen takes Michael Morgan to the Wall to prove that Damien is the Antichrist, the ruins begin to collapse, killing Morgan and Bugenhagen and burying Yigael's Wall again.Seven years later, at least two pieces of Yigael's Wall were recovered from the ruins of Megiddo, one of which was the part of the Wall which the image of Damien as a teenager was painted onto. The Wall's image of Damien as a teenager was mostly scratched away, but the face survived. These pieces were shipped to New York along with numerous other artifacts from Megiddo.
When Richard Thorn goes to New York, he finds the pieces of Yigael's Wall in a cargo carrier. When Richard sees Damien's face on the Wall, a runaway locomotive pushes the cargo carrier into another, destroying the pieces of Yigael's Wall.
Yigael's Wall was the wall of a chamber in Tel Megiddo. It had numerous images involving the original Antichrist, Damien Thorn, painted onto it. The first image was what appeared to be a jackal engulfed in flames; presumably representing Damien's birth of a jackal. The Wall also has four images of Damien from different points throughout his life, from birth to downfall. The first image is of Damien at the age of five, and another image is of him as a teenager.
