The Fey Realm is one of many names given to a strange plane or dimension similar to the natural world. It exists alongside the natural world, and is mostly a place of lush verdant woodland.
The Fey Realm is inhabited by many Fey beings, and even has thriving populations of elves and other sylvan creatures.
There are many places where the barrier between the realms is thin; a person knowing how to find such a place, or even an unwary traveler, can easily find him or herself in the Fey Realm. The Fey themselves call such places ‘Crossroads’.
Explorers of the Fey Realm report that there are many correspondences between the Realms, however, it is dangerous to expect too close a similarity. One thing is known for sure; time moves differently between the realms. There is many a tale of a hapless youth wandering into the Fey Realm and dallying with a handsome fey, only to return to find all their family have died many years ago.
That said, there are those who trade between the realms, or even use the Fey realm simply as a short cut, both to places in the Natural world and the Shadow Realm. One such stable crossroad is found variously at the Isle of Lost Dreams, the Isle of Lost Souls and the Isle of Fey Dreams.
Other crossroads are one way, or only connect two of the three realms, and some are semi random in nature.
Scholars have suggested that the Magic Points in Alfheim might be such crossroads.
One area of the Fey Realm is the Shatterstone Vale and the woodlands claimed by the Winter Court. This area has in the past been the location of savage conflict. The elves of the Winter Court swore to wipe out the shapeshifters of Shatterstone. Whilst the shapeshifters (many werewolves and wererats among them) had certainly raided the elven lands in their hunts, it could be argued that the elven leaders were motivated by aethetics rather than by a desire to do good.
This conflict, known locally as the War of the Pelt, was settled decades ago, and the two peoples now live in uneasy peace.
