Elidon

Elidon is a Unicorn, and the mate of Lamorna. The two of them dwelled on a rocky island atthe center of Wayward Pool in the Feywild Domain of Prismeer. After the imprisonment of Zybilna, the Pool became part of the splinter realm of Thither. Elidon was captured by the Hags of the Hourglass Coven. His horn was taken, and he was transformed into a flying rocking horse called Sugarlump by Skabatha Nightshade.
Skabatha kept Elidon imprisoned in Sugarlump's wooden form for a long time, and Lamorna was unable to locate him, but she remained sure that he was not dead. Elidon's horn was traded repeatedly through the hands of the Hourglass Coven, but it was eventually stolen by Will of the Feywild during one of his raids on Loomlurch. He had no idea of its value, so the Getaway Gang made the horn part of the unicorn costume they used to get healing water from Wayward Pool. It was eventually reunited with Elidon by the Witchlight Court, and the unicorn fight Skabatha by their side. After she fled Thither, he gave the Court his thanks and returned to be reunited with Lamorna again.
