Plane Sailing
Astral Admin - Mwahahaha!
Now if the DM really wants to mess up players minds...
They enter a series of rooms full of thick mist.
Halfway through the series of rooms they pass through a gate onto the ethereal plane, with walls of ethereal stone, and they see things in the material plane as misty images
They come across the enemy wizard - but they are unable to assault him, because they are ethereal. He has See Invisibility up, so he can see them... and he can target them with force effects such as magic missile!
They could face pretty nasty casualties if it takes them too long to work out what is going on...
