Meanwhile, Elsewhere in the Dungeon

[MunchkinMan]

In a quick scan of the Glossary, I found an entry for "Empty Room" which does a very fine job of answering that question. I'll not try to quote the whole thing here, but the basic gist is that an empty room contains no Monsters and no Munchkins. I suggest reading the glossary entry because there is more to it than I just wrote.

This is a fine opportunity for me to say, "Read the glossary, folks. It's more than just a lot of definitions." Seriously, you should read it since there's plenty o' useful information in it.

Also, I'd like to add that unless cards use the exact same or extremely similar text (which the two mentioned here don't), you shouldn't use one card to infer the behavior of another card.
