The Infinite Realms of the Faerie were created when the First Gate between Lysia and IIo formed. Frequently referred to as the Realm Between, it is true that the Faerie Realms occupy a location that is magickally between the Realms of Lysia and IIo. The Faerie Realms are made up of the Firmament and the Mist, but are most commonly described as a series of floating islands radiating out from Oberon's Castle at the exact center of the Faerie Realms. Furthermore, the islands are segregated into Topside and Underside--Topside is the home of the Seelie and Underside is the home of the Unseelie.
