A view into the Time Portal

Grimm peers over the edge of the roof into the black hole in space that floats in midair. His best friend Hannibal Callahan just jumped into the portal, vanishing in a blaze of lightning and fog. Callahan was following his girlfriend Mariel, who summoned up the portal after brutally killing three gangsters downstairs. Although Grimm can't see the bottom, or any trace of Mariel or Callahan, he grabs up some things and follows them through....

This photo shows the view that Grimm got, looking straight down into the portal from above. The walls of the portal are made of fabric. The fog at the bottom is created by large CO2 fire extinguishers. Lightning flashes were achieved with camera flash units. At the bottom of the portal were two pole-vaulting mats, so that the Investigators would land safely after jumping from the roof of the building. Kokens surrounded the mats to act as spotters and prevent anyone from bouncing off.
