All men looked with sorrow upon the sons of Turenn. Any of the seven _geasan_ of this eric that Lu put upon them was more than enough for any hero: how then would they survive till the last, or, having survived, how would they bring back with them these things, and how escape the wrath of Mekween and his sons? Nevertheless, the sons of Turenn were now under bond, and they had no choice but to do what they could to fulfil their eric. With sad hearts they left the great beauty and wonder of Tara, and with sadder hearts still reached their own land. Here with sorrow they bade farewell to Turenn their father and to dark-eyed Enya their sister, whom they loved so passing well, and to all their kindred and folk. Thereafter they set forth on their long and ever more and more perilous quest. It would have been easy for the sons of Turenn to have passed over into Alba, and sought service with the king of that country; or to have gone among the Kymri in the inland highlands beyond the isle where Manannan had his home: or southward to Lyonesse or into Armorica. But honour is a better thing than ease, and it would ill have befit heroes such as Brian and Ur and Urba to have evaded their solemn troth. A bitter wrong they had done, because of the hereditary feud betwixt the clans of Turenn and Kian: but now there was one thing only to do, and that to fulfil the eric put upon them by Lu, son of Kian. Moreover, Nuadh the Ardree and Bove Derg, son of the Dagda, and a score of the noblest lords in Erin were their warranty that they would do this thing. So, one day of the days, they set forth from Erin: and sad indeed were they when across the foam they took their last look at Dun Turenn and at the dear familiar hill of Ben Edar. * * * * * For that night Peterkin heard no more of the story of the Fate of the Sons of Turenn; but all the next evening, and the next again, he sat entranced by the strange moving tale of how Brian and Ur and Urba one by one fulfilled the hard and perilous conditions of their eric, and this until the sixth was done. But here, now, this tale cannot be told in full. To tell it aright would need a volume not less than this is. It must suffice that after innumerable hardships, after fierce cold and fiercer heat, after hunger and thirst and daily perils by land or sea, and strange and frightful encounters, and hazardous fights with monsters and wild men and kings and princes, the sons of Turenn found themselves sailing towards the remote north of Lochlin, having accomplished the six seeming impossible conditions.
