Control, Another random Game ending...

The Slide Projector (OOP15-UE) is an incredibly dangerous Object of Power discovered by the Federal Bureau of Control on September 14, 2002 before being contained in the Oldest House.
The Slide Projector is capable of projecting slides which act as doorways to other dimensions. Entities from these locations are capable of using the doorways to enter ordinary reality. Presumably, the slides are difficult to close, as both Jesse and Dylan Faden were unable to deactivate the Slide Projector without external aid. The Slide Projector's effect also only appears to work on the slides it was originally discovered with. Notably, the Slide Projector's effects activate even when it is not bound to any parautilitarian, and no Bureau parautilitarian has ever successfully bound the object.
