The military facility that came to be known as Simmonsville was used by Jason Wynn as the home of Project Ragnarok. It was here that 47 test subjects were experimented on in an attempt to creat a superhuman.

Wynn had originally schemed of creating a human/angel hybrid and negotiated the project with agents of Heaven. But secretly, he accepted a deal with Hell to deliver a perfect human subject to become the next hellspawn.

After Ragnarok was shut down in failure, the site eventually became the location for the military testing of a substance called psychoplasm, or necroplasm. Wynn had brokered a deal with the demon Malebolgia to obtain the substance. The name Simmonsville was coined because the Necroplasm fused with the memories of Al Simmons and created an evil collage of his past.

During testing, Simmonsville became the battleground for the first confrontation between Spawn and a Redeemer. Afterwards, it was mostly burned to the ground by Spawn.

Years later, two former patients of Ragnarok: Jim Downing and Richard Masullo, made their way to the remains of Simmonsville to find clues about their past. There they learned much of what they wanted to know from Jason Wynn himself.
