Aoife was a changed woman now and one day suggested that she and the children should visit their grandfather. On the journey they stopped by a lake and she encouraged the children to go for a swim. The four children played happily in the water, not noticing that their stepmother was now standing at the waters edge wearing her fathers magic cloak.
'For too long you children have stood between your father and I, but not for much longer!' she cried
'We cannot be killed by you...' Aodh replied,
'...we are the Children of Lir and if you harm us our ghosts will haunt you!'
'I’m not going to kill you.....' she shouted
'......but I am going to change you!'
At this she bowed her head and started an incantation. The children looked at each other in fear as they saw a red and gold circle envelope them on the water. They saw Aoife open up her cloak from which the great light of a fireball emerged and hurtled towards them, burning all in its wake.
The fireball hit the water and caused masses of steam to rise about the children and they soon lost all feeling in their legs, arms, shoulders and head. They soon regained their sight only to see Aoife laughing at them. Aodh tried to attack her and flailed his arms about furiously but nothing happened except the splashing of water. He turned to look at his brothers and sister only to see that they had all been turned into the most beautiful swans ever seen.
Aoife scowled at them again and told them that they were to spend nine hundred years as swans, three hundred on Lough Derravaragh, three hundred on the Straits of Moyle and three hundred on the Isle of Inish Glora. To end the spell they would have to hear the bell of the new God.
'I leave you with your voice however, and the most beautiful singing ever heard' she said. ; Children of Lir, Excerpt.
