"Follow me," said the warrior, "and you shall shortly have tidings of him." Then they followed the strange horseman into the forest by many dark and winding ways, until at last they came into a rocky ravine, where they found the mouth of a great cavern opening into the hillside.
Into this they went, and the way led them downward until it seemed as if they were going into the bowels of the earth, until at last the light began to shine round them, and they came out into a lovely land of flowery plains and green woods and singing streams.

In no long time thereafter they came to a great royal Dun, where he who led them was hailed as king and lord, and here, to their joy, they found their comrade, Dermot of the Love Spot, who told them of all his adventures and heard from them of theirs.

This ended, and when they had been entertained and refreshed, the lord of that place spoke to Finn and said:-- "I have now, O Finn, within my fortress the fifteen stoutest heroes that the world holds.

To this end have I brought you here, that ye might make war with me upon mine enemy the Champion of the Well, who is king of the land bordering on mine, and who ceases not to persecute and to harry my people because, in his arrogance, he would have all the Under World country subject to himself alone.

Say now if ye will embrace this enterprise and help me to defend my own: and if not I shall set you again upon the land of Erinn." Finn said, "What of my fifteen men that were carried away on the wild mare's back oversea ?" "They are guarding the marches of my kingdom," said the King of Sorca, "and all is well with them and shall be well." Then Finn agreed to take service with the King of Sorca, and next day they arrayed themselves for fight and went out at the head of the host.
