Celtic Myth

So, this is a Celtic myth. A while ago,  people from Spain want to take over Ireland. So, they go there and ask the goddesses of Ireland to help them. The first and second ones weren't much help but, the third one said that it was prophesied that the spanish would come. The Spanish said that it would be by themselves that they would win. This angered the third goddess. Then the spanish went to the goddesses' husbands.The gods advised that they should go home.So they did but, they changed their mind. This angered the gods. They sent a storm to stop the spanish. The Spanish (now to be known as the attackers) knew that if the storm was magic it would go no further up then the mast. It was magic . The third goddess calmed the winds. So then the leader of the attackers went to go take over the Irish. He did, but living was hard, so he made a treaty. The Irish would live underground. And the attackers would live on top. Underground was called the Otherworld. The Otherworld was where all the cool magical creatures lived.
