Where is the dragon?
You will not be able to face the dragon until you have reached the proper level. When you are ready, the path will become obvious.
Why can I not beat my master?
You may need more experience, better equipment, or more hitpoints before challenging your master again.
What should I do when I die?
Death is temporary. Explore the shades and graveyard until the next new day or until you find a way back.
