Fred follows the lava towards it's source.
From Create Your Own Story
As Lord Fred reaches the source of the lava, he is surprised to find an underground volcano residing deep in the caves. It is spewing a molten river of lava which flows in three different direction including the direction that he came from.
As Fred looks around the cavern, he noticed a door attached to the vertical slope at the base of the volcano. "How odd!" mutters Fred.
