Room 2

…a bright room whose walls were in some disrepair. The floorboards creaked and groaned; the plaster made a gritty sound.
They studied the old frescoes for clues but missed the obvious signs.
"Are we on the right path?" they asked.
Keeping in mind what a relative term "right" is, I assured them they were, indeed, on the right path. As for the “correct” path or the "most appropriate" path…. Well, that might be something else.
Full of confidence now they marched out to… Room 12 Room 22 Room 29

Solutions
