Soundlessly they launched the great galley again, and once more set sail. The night-wind was from the south-east, whereat they rejoiced, for thus there was no need of the oars, and so no betraying thresh would be heard.
When they were well north of Lismore they put out the long oars and swung the galley northwards. It was with relief that the sons of Usna passed the Appin lands, and before dawn rowed into a great sea-loch.
There, however, they learned that the King of Alba, he who had called himself Angus Mudartach, was in the westlands only for a brief while, and would have to haste to Dunedin straightway, as runners had come with tidings of a great rising. He had no rath of Dunchraig, and no dun there; and so in truth the sons of Usna knew that the king had lied to them, and that Darthool was right. As for Fergus of the Three Duns, he was no longer a great lord, but had been despoiled, and at the most could summon two score and ten men.
So the sons of Usna greatly rejoiced, for now they could go to their own land in safety, which lay beyond the region held by Fergus of the Duns.
For seven days they stayed by the shores of that sea-loch, under the shadow of mighty mountains. Ardan, with a scanty following, went through the hill-passes, and returned saying that the King of Alba had gone to his own country and that all the great lords of the region had departed with him, including Fergus.
So on the eighth day the galley sailed a short way southward once more, and entered into the Bay of Selma. There, on a rocky eminence, were the walls of their great dun, which Usna their father had built among the ruins of the chief stronghold of the Cruithne, the ancient people of Alba.[19]
It was with joy that the sons of Usna saw once more the house of their childhood, and with still greater joy that they found the people of the neighbouring glens and straths still loyal to them. Their father Usna had ever been at war with the King of Alba, and after many battles (the bards sang of the beauty of Usna’s wife as the torch that lit those wars) he had conquered all this region. But at his death, by treachery the king had overcome the stronghold and destroyed it.
But now again the sons of Usna had their home in their own eyrie. They knew not how long they might abide there in peace, for either the King of Alba, or Fergus of the Duns as his leader of men, would come again when once peace in the eastlands was secured.
There Nathos wished to dwell alone with Darthool and a few followers, but Ailne and Ardan once more refused to leave him then or ever. But glad were the thrice fifty vassals to return to their own land, and without regret the sons of Usna saw them set sail for Erin. They were men who cared little for aught save strife, and when not wielding sword or spear were haughty and bitter with all other men save those of the Red Branch, and so were only a danger and a weariness in that place.
Throughout that winter they lived there in peace, hunting and fishing. So great was the love of each for Darthool that every day was full of peace and content wherein they saw her. Nathos moved in a dream, and knew the extreme of joy. At night, before the fire, Darthool sang to them old-world airs of a sweet plaintive music, so sweet and plaintive that men said she must be no other than Fionula, she of the children of Lir who were turned into wild swans, and lived a thousand years in the old, old days.
