A banshee is a female spirit Irish mythology. She cries and screams at the death of a person. In some stories, she appears as an old woman or as a beautiful young girl and her screaming, usually at night, predicts the death of the person hearing her.

One day, she took the children to a lake called Lake Derravaragh. While they were swimming, she cursed them and turned them into swans.
Only the sounds of a bell of a new god could change the swans into humans again.
Then St. Patrick brought Christianity to Ireland and the children heard the bell and became humans again.

According to legend, fairies sometimes give birth to deformed babies. When this happens, the fairies take a healthy human baby and leave their deformed baby in its place.

The harp is the National symbol of Ireland and appears in many of its ancient legends. The most famous Irish harp belonged to the Dagda.

One day, the dark-haired people stole the Dagda’s  magic harp. They hung it on the wall of any empty castle and sat down to eat. While they were eating, the Dagda broke the door and entered the castle. His enemies ran to kill him with their swords, but he called his harp and it flew into his hands.
