Blue and orange shafts of light
A Shaft of Light is a short distance portal found on level 3 of the Tomb on the Isle of Prisoners. A series of levers configure how the shafts. If properly configured, the blue shafts of light advance the user through a series of gated sections in a long hallway. A hissing sound indicates the correct configuration and movement. Whereas a laughing sound signals an incorrect configuration. The orange shafts will always return the user to the levers, found just a short distance away.
