That night, they leave the castle with Glimfeather the owl and another owl, who take them to the Parliament of Owls for the full story on Prince Rillian. Glimfeather's friend (whose name is not mentioned) tells them that the Queen of Narnia had been killed by a vile serpent in the Narnian woods a few years earlier, and her son Rillian had gone back to the forest several times in hope of destroying the serpent, only to find no sign of it at any time. After a while, Lord Drinian (another of the King's lifelong friends) confronts Rillian and orders him to stop trying to find the serpent, as it is too dangerous. Rillian then told Drinian to come with him to a part of the forest, where a beautiful lady appears. Drinian's horse suddenly makes a noise, and frightens the lady away. The next time Rillian went out, he failed to return. Drinian later spoke to Caspian about his and Rillian's visit to the forest, and urged the king to "slay him speedily" as a traitor, but the king could not go through with it - he had lost his queen and his son, and it would be too much for him to lose his friend as well.
