Then the fairy said to the witcher: "I will tell you what to do: put on a pair of iron shoes, pick up an iron staff. Walk in the iron shoes to the end of the world, pat the ground before you with the staff, and sprinkle it with tears. Walk through fire and water, do not stop, do not look back. And when your shoes wear out, and when the iron staff shatters, when the wind and the heat dry your eyes so that you cannot shed another tear, then you will have reached the world's end, and you will have found what you seek what you love. Perhaps."
And so the witcher walked through fire and water without looking back. But he took neither the iron shoes nor the staff. He took only his witcher's sword. He did not heed the words of the fairy. And that's a good thing, because she was an evil fairy.
