A great example of the 5 room dungeon, a format that appears to be the new hotness in D&D circles. I particularly like the formatting of the rooms that give you enough detail to describe the rooms well, without resorting to a bland box text that the DM would read out.

This would be great to throw ito an on running campaign in place of a random encounter and there's potential for expanding with your own ideas inot the launch of it's own adventure arc.
