My Favorite Children's Story

When I was growing up I use to love The King and The Pegasus.  The story is about an English  king whom everybody loved, but then one day an evil witch cast an evil spell over the good King's land.  The only way to restore his kingdom was to ride across a vast mountain range into forbidden land, and destroy the witch.  He looked, and looked for a horse that could make the hard, and nearly impossible journey, but the good King could not find such horse in his land.  So, he would have to walk the entire way a foot.  He had walked so far he didn't think that he could walk one more step.  Just then a big, beautiful, black, Pegasus, named Attean, with big iron feet, and an even bigger heart showed up. Attean told the good King that he would carry him the rest of the journey and back again.  Also, he had special powers that could defeat the evil witch.  So Attean and the good King went the rest of the journey together.  When they got to the castle where the witch lived,  Attean turned invisible and they flew right into her castle.  Attean conquered the witch by turning her into a fat bullfrog and locking her in her dungeon, where the good King's father died because he was captured by the witch.  So, Attean kept his word by taking the good King back to his kingdom.  Now the forest that they had to go through to get there was so thick that you could barely see the sky, and the path was very narrow.  So Attean could not fly in it.  He also could not fly over it because the trees were so tall that by the time he could reach the top the air was too thin to breathe.  So Attean had to walk through the forest.  On their way home, the road was blocked by a rock slide.  There was only one way through, and that was to go up the steepest part of the mountain.   So, Attean turned to the good King and asked him to trust him.  The good King said okay, and Attean started up the mountain side.  The good King thought surly they would both die.  But Attean reached the top, and took the good King home.  Everyone in the Kingdom greeted them with cookies, and coffee.  Then the good King turned to Attean and said "You have kept your word, and brought me home safely.  I now trust you with my life.  Will you please stay and live in my Kingdom?"  Attean replied "King you are one of the greatest Kings to ever rule these lands.  I was sent to you from your father to teach you one thing:  Only when you believe something can be done, can it be done, but if you believe everything is impossible, that is when nothing can ever be done.  I was a temporary gift from your father, and now I must return to him.  Your father and I will always be there for you if you are ever in need.  We are always watching."  Then Attean flew away, and was gone just as fast as he had come.  The good King smiled and as Attean flew away, up towards the heavens, and said "I will miss you Attean, and some day, I will join you, and my father forever... but not yet my friend, not yet."
