Miskito-Catholic Sacred Narrative

In religion class today, the Catholic Miskita teacher I collaborate with offered the following story as part of her explanation of the sign of the cross:

Lucifer was the greatest of all the angels, but he sought to be like God, so God banished him to the earth. He fell from the sky, and when he hit the ground he broke into many pieces. Some of the pieces became the evil spirits in the water, that are the mermaids, some of them the evil spirits in the wind, and some the evil spirits in the wilderness, that is the gnomes. So now we make the sign of the cross to ward off the evil spirits.
