narratorium
The material that is used when the narrator won't allow you to go somewhere because it's protected by plot.
Narrator: The entrance is barred by wooden planks, the only other way is to go through this really creepy labyrinth that is filled with monsters and will advance the plot.
Character 1: Couldn't I just burn the wooden planks?
Narrator: No!
Character 2: Couldn't I just fire my laser sword and disintegrate the planks or something?
Narrator: No!
Character 1: Couldn't I just melt it with my acid crystals or run it over with my working tank or maybe just chop it in half with one of my 7 axes?
Narrator: No!
Character 1: Why not?
Narrator: Because it's protected by a layer of plot/narratorium.
