Agatheron's Points of Light
If the Shadowfell is the “dark echo” of the world, then the Feywild is the “bright” echo. Yet, despite it being associated with the light, the Feywild can be as dangerous as the Shadowfell itself. Elves and Gnomes and other fey-folk who now live in the world can trace their origins here. Eladrin remain as the most populous residents of this realm, and are often encountered in the World itself.
The Feywild is a magically charged realm. It has been said that magical energy flows like rivers throughout places in this realm, and pools in the thin places between worlds. Corellon, patron of arcane magic, is thought to live here in the same way that the Raven Queen makes her home in the Shadowfell.
