It's a mixed bagg. Once you've entered, there are only two exits. One of them leads to certain death, and the other to happiness and prosperity. There are two wisened trees that will allow you to ask a single question, to which they will both give an answer. Only problem is that one of the trees always lies. The other always tells the truth, but there's no way to know which is which without asking a question. You can only ask one question, so better make it a good one....
