The Chosen One finds his destiny. Heiðar has followed his creator Sigmund to the mysterious Elven Castle on the Snæfellsnes Peninsula, where he must earn the key to the secret of immortality. The knowledge of immortality has been hidden in Iceland for a long time. With Sigmund's serpent-tongued half-brother Bekan stirring once again, the secret is more endangered than ever. Heiðar faces demanding tasks. At the end of his training, he must be able to tame the returned Evening Wolf in order to learn the secret of immortality at the summer solstice. Rúna suffers greatly from the long separation from Heiðar. Her heart becomes black and heavy, as if dipped in liquid tar. Lifeless, she sinks to the ground.
