The Feywild
The Feywild, also known as the Plane of Faerie is an echo of the Prime Material Plane suffused with potent magic and unrestrained emotions, and is considered the opposite of the Shadowfell. It is the place from which fey originated, and from where the first elves arrived in Eldareth.
As an echo of the Prime Material plane, its geography is similar although not entirely identical to that of Eldareth, but the natural landscape was markedly more dramatic and beautiful in the Feywild, with mountains standing straighter and sharper, rivers flowing clearer and faster, flowers bloom brighter and more fragrantly, and weather manifesting in supernatural ways. Strong emotions even altered the landscape of the Feywild itself, wilting flowers trailed the despondent or furious and carefree animals traveled alongside chipper and cheerful individuals
While most Prime locations and landmarks have analogues in the Feywild, sites of civilization in the Prime could be so unimportant in the Feywild as to be easily missed, while natural landmarks might be significantly more majestic or extreme. Navigating the Feywild is further complicated by the fact that distances did not always make sense.
Further complicating any visit to the plane was that time does not flow the same in the Feywild as on the Prime. While any visitor would experience time flowing as normal, it is often the case that more time is passing in the Prime, sometimes on the order of weeks, months, or years longer than expected. At the same time, those with no fey ancestry might find their memories of time spent in the Feywild going hazy, if not vanishing altogether.
Arcane magic runs more freely and powerfully in the Feywild than it does in the Prime, and it is for this reason that so many of its inhabitants and landmarks are suffused with magic.As an additional consequence of this all-encompassing magic, arcane spells tend to be amplified in power or duration when cast in the Feywild, and other times will manifest in entirely unexpected ways
Fey crosssings are magical portals which lead to the Feywild, a fold in reality's ends touched each other, thus allowing instant travel by stepping in one end and coming out of the other. They can be found all over Eldareth, but most are hidden from casual view. They often require the use of a ritual to operate, and after the Upheaval, many malfunctioned. Most crossings also have a fey guardian who has to be convinced to allow usage of the crossing.
