When Spawn attempted to stop the Forgotten Ones from sacrificing a little girl to Heaven, he submitted their ritual, The Ordeal, to spare her life.

In The Ordeal, he had to hold on to the Teind-child as she morphed into an assortment of beasts and attacked Spawn. She eventually appeared as Al Simmons himself and Spawn was forced to re-witness Al's death.

Spawn passed The Ordeal, thus saving the girl, but angering the Forgotten Ones in the process. They promised he would have to pay greater sacrifices because of his interference.

As it turned out, Spawn's interference was part of an elaborate plan by Mammon to free the Forgotten Ones of their pact of Teind.

A thief whose soul was damned to wander a forest in Japan forever. His ghost was occasionally seen running through the trees holding its own head, eyes cast down in shame.

When Ben Nakadai was lured into opening Mammon's box, Ori's soul was revealed to Spawn - who found the thief and finally laid him to rest.

A reality that intersects all planes of existence. The Overlap is filled with creatures from countless worlds and has no spiritual or physical laws. It is an elastic reality ripe for experimentation and discovery.

Two of its inhabitants, %^2 and %^9,experimented with the effects of nuclear energy on infernal matter by arranging for Spawn to be at the center of an atomic blast. They sent their fellow Overlap resident, Harry Houdini, to lure Spawn to the site.

Their experiment backfired when Houdini opened a dimensional rift and send the nuclear blast triggered by Yousef Volokhov to the Overlap. Yousef and his compatriots were sucked through the hole shortly after and became test subjects for the residents of the overlap.
