Apollo 11 Lunar Landing Hoax Set

Origin
In 1969, Buzz Aldrin, Neil Armstrong and pilot Michael Collins were part of the first manned mission to land on the surface of the Moon. In 1969, the moon landing was also faked by the United States government. While Aldrin and Armstrong did set foot on the moon, this was not what the American public and, indeed, the world at large, saw on screen.

Due to last minute changes in the mission relating to Cold War espionage and military preparation, it was deemed too risky to allow potential enemies of the state to observe what the cosmonauts were installing and it was too late to pretend the launch was not happening due the prevalence of media attention. Instead, a very convincing set of the lunar surface was hastily constructed using high-end telescopes and government agents were conscripted as actors to take the role of the spacemen.

Almost immediately after the monumental event there were skeptics. People who claimed that such a feat of science and technology could not have been possible and that the entire thing had been a hoax. They were, of course, right, in a sense. The achievement of fooling the world by not actually fooling the world, as well as the very vocal doubters of the landing, both contributed to the effects of the artifact.

Effects
When anything enters the set of the landing, still in perfect condition, it will begin to behave as if it were in the reduced-gravity environment of the moon. As soon as the limits of the set are reached, it will resume regular gravity and atmospheric influences. The biggest danger involved is that there is no oxygen on set, meaning someone who would wander in accidentally could find themselves in significant danger.

A secondary effects is that anyone who does enter the set will be surrounded by a field of skepticism and paranoia, with other refusing to believe their claims of truth unless they, too, have been on the set.
