The series draws on Celtic mythology and is about Ealdwood, a forest at the edge of Faery, and Arafel, a Daoine Sidhe.

[2] The Dreamstone was first published in 1983 as a paperback edition by DAW Books, and featured cover art by Cherryh's brother, David A. Cherry.

Arafel watched the coming and going of Men in the lands surrounding Ealdwood, but showed little interest in them, until one man sought shelter in the fringes of the forest.

She confronted him and learned that his king at Dun na h-Eoin had been killed, and that he, Niall, was on the run from those who had seized power.

Arafel tells him that he cannot stay in Ealdwood, but fearing for his safety, sends him to Beorc's Steading, a sanctuary hidden in a valley for "lostlings".

When Fionn discovers what Arafel did, and the distress it is causing her, he leaves her to find Evald to trade his harp for her stone.

They win the battle, but Evald is worried that the retreating enemy will overrun Caer Wiell, and asks the king to let him return to defend it.

Caer Wiell is besieged by An Beag, and Ciaran helps in its defence, assuring its people that their Lord Evald and the king will return to free them.

As Caer Wiell's siege worsens, Ciaran calls Arafel for help via the stone, unaware of the dangers in summoning the Sidhe.

"[2] The Rambles cultural arts magazine described the Arafel's Saga omnibus as "an epic tale of magic and adventure" and recommended it to anyone interested in legendary Fair Folk.
