The Pandora Directive
Note: in case you lose your orientation, the following observations
may prove helpful:
- The north door (in any room!) is always a 'star' door ('S' in the drawing).
- The south door is always a 'moon' door ('M').
- The east door is always a 'white sun' door ('W').
- The west door is always a 'black sun' door ('B').
