The Hedge is the name for the plane that seems to act as a buffer for the feywilde. Most who try to enter into the feywilde form another plane will come into the Hedge.  The Hedge is a amorphic plane of nature.  Any type of landscape can exist within the Hedge. These landscape are often very hostile to the traveler and can be deadly.  Navigating the Hedge successfully will bring one into the Feywilde itself.  True Portals can bypass the Hedge. As they are usually made form the Feywilde to another plane. What the Hedge ends up being seems to be linked somehow to the those entering it and the location they are entering from.
