Setanta was still improving his martial arts skills in the kingdom of Donegal when he received a letter from the laird Fergus and returned to Dundalk. Setanta should be 16 years old and laird Fergus intended to tell the young man about his origins. The laird was convinced that Setanta was the bastard of King Conaire, since Deichtine was the king's concubine. Laird Fergus was unaware of Deichtine's encounter with the stag-Cernunnos, the incarnation of the god Lugh. Setanta, after the death of the king, must inherit the Sacred throne of Tara as sole heir. And he is ready for it.
However, before the coronation, he decided to visit his fiancée Emer. For this, he and his friends went to Uisnech. It took several days to get to Uisnech. And at one of Setanta's overnight stays, one of the ancient heroes of Ireland appeared in a dream and presented the future king of Tara with the legendary sword Claiomh Solais, which means: The Sword of Light.
After that, Setanta met an inhabitant of the Other World, Fand, who was in love with a young man. She promised to take him to her legendary Land of Youth when the time comes. Setanta reached Uisnech safely and met his fiancée. They spent several days together. On the way back to Dundalk, Setanta and his friends meet Banshee in the guise of a huge black bird. And this meeting portends trouble. To be continued.
