"King of the Golden Mines," she said, "I know your story, and have the power to set you free. I can also restore your Princess All-fair to you once more. Now, as I am an enemy of the Desert Fairy, I will do this for you."
The King thanked her, of course, and the mermaid bade him set himself upon her tail, and away they sailed at full speed across the blue ocean until they had gone many miles.
"The Princess, you must know," said the mermaid, "is being kept a prisoner by the Yellow Dwarf. She is in a bright steel castle, and in another hour we shall reach the place."
On they went still farther, and at length the mermaid set the King down upon the seashore.
"The rest of the journey," she said, "you must take alone, and you will have many enemies to fight before you reach the Princess. But," she added, "I will present you with this magic sword, which will overcome everything, so long as you never let it out of your hand."
The King took the sword, and thanked the mermaid again and again, and then he set out to seek the steel castle.
But before he had gone a hundred yards, four terrible griffins attacked him, and the King stood a good chance of being torn to pieces by their long claws. Just in time, however, he remembered his magic sword, and no sooner did the four griffins behold it than they sank to the ground, blinded by its brightness.
After that it was an easy matter to cut off their heads, and the King went on his way again.
