Void Pit
HAZARD 20 +0 or Detect Magic
An ice-caked pit with no bottom looks out into the depths of space.
DC 48 Thievery (legendary) to deactivate the pit's magical link to outer space or Dispel Magic (10th rank, counteract DC 44)
Beyond the Barrier
A creature within the pit takes three consecutive Interact actions to push their way through the barrier in the pit
The creature is pulled through the portal into the depths of space. It can attempt to Grab an Edge with a DC 42 Reflex save, otherwise it discovers the portal is one-way—no return route to Golarion exists. The creature takes 10d6 bludgeoning damage (DC 42 basic Fortitude) at the start of each turn and begins to suffocate. Without powerful magic like Interplanar Teleport or Wish, even a creature that can survive the depths of space will be lost forever—as the Void Pit deposits them in the unimaginably vast gulf between galaxies in which sound cannot exist, where they cannot cast spells with verbal components.
The Void Pit resets instantly.
