" It was by this method that he was said to protect the Isle of Man from discovery.
Manannán was associated with a "cauldron of regeneration". This is seen in the tale of Cormac mac Airt, among other tales. Here, he appeared at Cormac's ramparts in the guise of a warrior who told him he came from a land where old age, sickness, death, decay, and falsehood were unknown (the Otherworld was also known as the "Land of Youth" or the "Land of the Living").

In Irish mythology, Áine (pronounced "awnya" or "eye-na" is a goddess of love growth and Cattle, also perhaps associated with the sun Manannán had a daughter, whose name was Niamh of the Golden Hair.

Fiachnae mac Báetáin, also called Fiachnae Lurgan or Fiachnae Find, was king of the Dál nAraidi and high-king of the Ulaid in the early 7th The historical Mongan was a son of Fiachnae mac Báetáin, born towards the end of the 6th century. Fiachnae mac Báetáin, also called Fiachnae Lurgan or Fiachnae Find, was king of the Dál nAraidi and high-king of the Ulaid in the early 7th According to legend Fiachnae, who was at war in Scotland, came home with a victory because of a bargain made with Manannán (either by him, or by his wife) to let Manannán have a child by his wife. This child, Mongan, was supposedly taken to the Otherworld when he was very young, to be raised there by Manannán. The Compert Mongáin tells the tale.
Despite not being the biological father of many children, Manannán is often seen in the traditional role of foster father, raising a number of foster children including Lugh of the great hand and the children of Deirdre.

His helmet had two precious stones set in front and one behind, which flashed as he moved. And Manannan girt him for the fight with his own deadly sword, called the Answerer, from the wound of which no man ever recovered, and those who were opposed to it in battle were so terrified that their strength left them. " Lugh also took Enbarr of the Flowing Mane, and was joined by Manannan's own sons and Fairy Cavalcade. When he looked back on leaving, Lugh saw "his foster-father's noble figure standing on the beach. Manannan was wrapped in his magic cloak of colours, changing like the sun from blue-green to silver, and again to the purple of evening. He waved his hand to Lugh, and cried: 'Victory and blessing with thee!' So Lugh, glorious in his youth and strength, left his Island home. "
