Once upon a time, there were two siblings very different in their characters from each other. Uma was gentle and confident while Ivan was irritable and a little suspicious. But they both loved each other very much, and had in common doing adventures together. On the other side of the lake, and up the hill, on top of it, there were ruins of a castle that, in its good old days, had belonged to a king, and owner of the whole region. Today only its ruins remained. And there was a fence with a big sign that read: "FORBIDDEN- NO TRASSPASIG - DANGEROUS ZONE" People in the town were very afraid, and they didn't even come near the place because of many legends about the castle had been woven "We have arrived at last!, said Uma to her brother, is that the tower where they locked him up? she asked breathlessly. "Yes! that's the one. The only one still standing. They went in very carefully, for the evening had fallen, and it was getting dark. A great undergrowth had invaded everywhere, preventing them from advancing, as well as the scattered stones of the walls, making piles. The majority of the tiles were loose and broken. Inside what could have been the grand hall of the throne, you could see the tapestries dingy with the passage of years. There was the melancholy groan of the wind as it sank into the tower echoing in pain. When we look through its surroundings, they tell us about a sad story, but, it has a great end because it is the one that deserves. And, who wants to read a story with a bad ending?

As for being able to convert lead into gold, in theory it is not impossible, but in practice it is.
