In "The Dreamstone" Arafel, a Daoine Sidhe helps Ciaran, a halfling (half human, half elf) save Caer Wiell near to Ealdwood forest, the last remaining bastion of Faery on Earth. "The Tree of Swords and Jewels" continues the story ten years later, when Ciaran has married Branwyn and become Lord of Caer Wiell. All of Caer Wiell are aware of Ciaran's connections to the Sidhe, whom they fear. One day Arafel visits Ciaran and returns elf prince Liosliath's dreamstone to him, saying that she needs his help: dark forces have awakened again and have overrun part of Eald (Faery). Ciaran tells her that peace in the region is fragile: King Laochailan does not trust him, and Ciaran's brother Donnchadh of Caer Donn fears him and his elf heritage.
