Cáilte then spent six weeks in the Immortal World dining with his men. He met Saint Patrick at Usnach (pron. WISH-na) presented him with the craebghlasach: Fionns Sword, escra: Fionns goblet of gold, and boar as gifts. He told legends of a water monster, Fernas Ford, and the Valley of the Three Waters over a meal of salmon. Cáilte and Conall mac Neill: Reed Divine Son of Cloud then went to ráth Artrach: Arthurs Womb in the north and told local people place-name legends. They then journeyed to lochan daimh dheirg: The Red Stags Loch, ráth Áine, : River Womb and foradhn na fénne: Seat of the Fianna: White Ones. Saint Patrick appeared, the stories of the three places were written down and faery music put the party to sleep. Dubhsliabh: Black Mountain Well was then renamed bas Phátraic: Patricks Palm A druid priest from the Immortal World appeared and asked for the story of sea-god Manannans Cairn. At glenn an scáin, where Saint Patrick had been enslaved, the Princess Étáin: Emerald Goddess gave Saint Patrick fifty ingots of gold and silver and he granted her brother kingship of Dalríada province. Cáilte then told the stories of tonn chlíodhna: Wave of Clenna, tonn téide, and ráth Medhbha: Inroxicating Ones Womb. Scothniamh: Flower-lustre appeared and Cáilte gave her gold for a marriage gift. He explained to Saint Patrick that she was young because she was an immortal goddess; while he was old because he was a Son of Mil. Saint Patrick pronounced Mass and after the legend of Hag Glen they all went to Leinster.
The King of Leinster, Dunlang, told Saint Patrick the King of the Decies had declared war. Saint Patrick had the earth swallow the rival king. One third of the children and wealth of Leinster was dedicated to Saint Patrick at a feast. Saint Patrick then blessed the stone of leac na gcéad, went to the Rath: Womb of Wonders, and finally to Connaught. At the palace of Connaught Cáilte told the geneology of Fionn to the King and three ravens of the sidhe healed him of sickness. They then said goodbye and went to the Liss of Women where Cáilte played chess with Saint Patrick at carn na finghaile and declared Saint Patrick priest of all Ireland. At Taras feast Cáilte told Saint Patrick of the marvelous Stone of Destiny: Lia Fáil. It would cry out when the rightful king of Ireland touched it, turn black with lies, and pink with truth. (25)
