LEGENDS are important sources of true information. They always turn out to be far more accurate than HISTORY. Listen and attend carefully if anyone recounts you a Legend. The person telling it may be an old HERBWOMAN, a BARD, a bad KING, one of your COMPANIONS or just someone in an INN. But no matter how improbable the story, it will turn out to be the exact truth and only by following it accurately can you hope to succeed in your QUEST. The Management will never allow anyone to tell you a Legend unless it is going to be important for you to know.
