Okay, this has absolutely nothing to do with anything currently being discussed, but I thought I'd post it anyway.
Players, on Kulthea, stumble across a Lords of Essence facility - still partially functional. One thing in the facility is some sort of transportation portal that connects to another, working facility on one of the moons (obviously not Charon or Orhan). The players end up in a place with lower than normal gravity in areas, completely hostile exterior environment, dangerous defence systems and possibly, because it isn't on Kulthea - no working magic.
