Popular legend tells how, one day, the master of Cal Feu in La Guàrdia was travelling to Organyà with his servant via the Collada (col) del Pillat. When they arrived at Arreposador, the master realised that he had left at home the container housing the manairons; small, brave beings that can be captured from a plant on the night of Saint John, whenever there is an old moon.
-Ton, you must go back home and tell my wife to give you a container that I have on my bedside table, but you must not open it, regardless of what may happen.
The servant generally did as his master told him, but he could not resist the temptation to pry and to find out more about the container. He opened it and straight away a group of obsessed manairons emerged from the container, demanding him more and more work to do.
-Turn as much of the rock into scree as you can –Ton ordered them, frightened and surprised. When it seemed to him that the manairons had started to do a bit too much work, Ton tried to convince them to go back into the little box, because if not...
The surprising and even inexplicable rock scree and debris that can be found in the Obaga forest of La Guàrdia provide proof of this story.
