Reverse Spirit Realm Gateway
The Reverse Spirit Realm Gateway was a machine Frankenstein-818 was forced to build by the Great Ghost on Halloween 2019, as an inversion of his original Spirit Realm Gateway.
After the original Gateway malfunctioned. Frankenstein insisted on “repairing” it himself despite not understanding what had caused the malfunction, and did so by haphazardly removing a bunch of parts. Conscious that it may not actually work, he added a holographic projector to fake the appearance of some ghosts, though this didn't fool anybody. Predictably, once switched on, the Gateway collapsed into a full-blown, two-way dimensional rift which allowed the Great Ghost's legion to cross into the Cupid Homeworld, from which they stole a fleet of Fog Ships, heading off into the Multiverse to find bodies to possess. After they left, Frankenstein built a portable One-Way Forced Spirit Realm Gateway that could send them back if activated in their presence.
However, the spirits soon returned to the Homeworld, hoping to summon more of their own, only to find that the Department of Rifts had successfully closed the Rifts. This drove them to abduct Frankenstein-818 to force him to build a Reverse Spirit Realm Gateway in an abandoned Prime Earth theatre, which would only allow spirits to cross from the Spirit Realm into the Prime Universe, and not the other way around. In the end, however, this device proved their undoing because Frankenstein had built it as an exact reversal of his original designs, including the turning-Cupids-into-ghosts setting, which meant that the Reverse Gateway instead turned every spirit who passed through it into a small clockwork toy version of itself.
