Often, they just sat there on the shore, braided her blond braids, singing softly to himself. One day the sorcerer of Masaré past the lake, she heard singing and fell in love with the mermaid. With all of his magic power he tried to kidnap the lovely fairy, but they did not catch themselves.
So the sorcerer finally asked the witch Langwerda for help. Langwerda advised him that he should dress up as a jewel merchant and the Rosengarten Latemar to conjure a rainbow. Then he should go to Lake Carezza to attract the Virgin and kidnapping.
Said and done. But one forgot the evil warlock: to dress up.
The water fairy gazed entranced the beautiful colors of the rainbow and the many gems, she noticed but also the magician who was hiding on the shore and suddenly appeared again under the Lake Carezza. Since that day, she was never seen again.
The sorcerer was about the failure of the planned kidnapping so angry that he in his lovesickness tore the rainbow from the sky, it crashed and all the rainbow pieces with the jewels cast into the lake: this is the reason why the Lake Carezza rainbow colors today in the most gorgeous shimmers and is called by the Ladin "Lec de ergobando", the Rainbow Lake.
