The Stag answered: "When first I came here this great forest was a vast plain, in which grew one little oak sapling. This sapling became in time an oak-tree, and after its long lifetime gradually decayed until it became this stump. Now, an oak-tree is three hundred years in growing, three hundred years in its full strength, and three hundred years in its decay. Yet in all this time I have never heard aught of Mabon, son of Modron. But, since ye are Arthur's knights, I will take you to one who was made before my time." Then he led them to the Owl of Darkdingle. "When first I came here," said the Owl from his dark cavernous home when he heard their question, "this valley was covered with a vast wood. It decayed away, and another grew up, and after that had withered away, a third, which now ye see. But never have I heard of the man whom ye seek. Yet, since ye are Arthur's knights, I will take ye to the oldest creature in the world--to the Eagle of the Aldergrove." So thither they went, and when he heard their question the Eagle answered: "When I first arrived, there was a rock in this place so high that I could perch on its top and peck at the stars, and so long have I been here that now it is but a few inches high. Never have I heard of this man save once, and that was when I visited the Lone Lake. There I stuck my claws into a salmon, hoping to kill him for my supper; but he dragged me into deep water, so that I barely escaped with my life. But when I went with all my band to slay him, he sent ambassadors, and made good peace with me, and came and begged me to take fifty fish-spears out of his back. He, if anyone can, will tell you what you want to know, and I will be your guide to him." So they journeyed on till they reached a great blue lake, hidden in the depths of the forest, and there they found the Salmon of the Lone Lake. He heard their question, and looking at them very wisely, replied: "Such wrong as I have never found elsewhere have I found under the walls of Gloucester Castle, on the River Severn, up which I travel with every tide. And that ye may know it is so, come, two of ye, and travel thither upon my shoulders." Then Kai and Uriel came down to the water, and stood upon the shoulders of the Salmon of Lane Lake, who swam with them down the Severn, and brought them under the walls of Gloucester Castle. "Hark!" said the Salmon; and as they listened, a voice was heard from the dungeon wall wailing in deepest sorrow and woe. Then Uriel cried: "Whose voice is this that moans within this gloomy cell?" "Alas!" wailed the voice, "'tis that of Mabon, the son of Modron, shut up eternally in the prison of Gwyn, son of Nith, King of Faerie. Here I, the Elfin Huntsman, ever young, am shut out eternally from the sight of wood and fell and the joyful chase which is my birthright." "Canst thou be ransomed with silver and gold?" asked Uriel.
