Hello.

Is dragon chamber considered as one room or two rooms? Can hero exit from every exit in the chamber or only from adjacent to his tile cell? For example, if there is a bottomless pit and two walls on on? side of the treasure chamber, does hero have to waste a turn to move to the other half of chamber to exit to an unexplored dungeon tile? Does he draw dragon card, if he has to move?

"Despite the fact that the Treasure Chamber occupies two
spaces of the dungeon, the Treasure Chamber is treated as a single
space." (p. 13)

Thanks. Didn't notice that.
