Eladrin of the Feywild
The Feywild is a realm that mixes a pristine natural world with the subtle flow of magic. Here the forests are alive and breathing, the plains are verdant and plush, the waters are clear and pure, and the sky is crystalline and clean. It is a plane that parallels the Realm of Men, just one step beyond the fringe of most beings perception. The eladrin share the Feywild with many beings, but it is perhaps they who are it's most prominent.
The cities and towns of the eladrin slowly, over time, drift into and out of the Realm of Men. These cities always materialize in potent areas of solitude and seclusion and might stay for a season, a year, or decades. Before an eladrin city slides there are always fissures between the worlds; portals that allow passage. Through these portals the eladrin will send scouts-
whom they call the Elidyr-who enter the Realm of Men to observe and learn the activities in the local lands. It is through the Elidyr that they discover how to prepare for their visit.
