You always thought the Fair Folk were a myth: Leprechauns aren't real, there's no gold at the end of the rainbow, and there's nothing inside those heather-covered hills but heaps of dirt. But when your brother vanishes into thin air on Samhain night, you start to have your doubts. All signs point to a magical realm contained deep within the hills! Discover the hidden world of the Aos Sidhe: Hear the wail of the banshee; visit the Gremlin mechanic; find the end of the rainbow; and face Medb, the formidable Queen of the Sidhe. Adventure is waiting for you in the magical world of Celtic Lore!
