- Based on the results, I'll assume what's behind the remaining doors with symbols: 1. a trap with deadly gas; 2. a corridor full of traps; 3. an unlit corridor; 5. a trap with sleeping gas. This part of the structure looks recently used and added much later, so it's possible that one of the corridors leads to important rooms. If, of course, they are corridors. Or maybe the "air" represents exits.
