So the brainstorm for a 4e Feywild project is going on at Fourthparty - even if you are like me and don't know much about 4e as a system you might enjoy throwing some ideas into the pot:

in an attempt to drag some cutters into this, here is the original pitch for this project:
Inspired by European folklore and popular magical realism and high fantasy, help cultivate the ripe and underutilized realm of Faerie for D&D. Lets develop thought-provoking elements intended for the DM in a place of magic and impossibility.
Wander the verdancy of the Weal, Faerie’s green, flowering face with all its intoxicating wonders. Or plunge into the horror of the Wan, where ugliness and envy have bore a second country of caves and darkness. Risk the boundaries of the Eald, where the old spirits linger, or dare the Warp, where the most beautiful fey are lured and twisted into prophetic hags.
In Faerie, poetry can move the sky to tears, and a song stir even a mountain into moving aside. Witness emotion take its place beside gravity as a tangible force, turning a lady’s favor into armor stronger than steel, and her scorn a poison deadlier than hemlock. Join in revelry that lasts for human lifetimes. Hear magic carry like a chortle on the wind. In Faerie, the heights of both honor and pettiness are defined. Overcome the tomfoolery of the base-born fey, and survive the ceremony and pomp of their royalty, fickle as children and powerful as demigods.
The 128-page supplement includes:
The Verge: 5 mortal/planar crossings along the edges of Faerie
+ added means of entering and escaping Faerie through skill challenges, terrain powers, rituals, curses, items, portals, NPCs, etc
The Splendor of the Weal: 8 brief and 4 in depth locations set on Faerie’s verdant face, the latter complete with sample delves
terrain powers and hazards, skill challenges, companions, diseases, poisons, etc
The Horrors of the Wan: 8 brief and 4 in depth locations set in Faerie’s subterranean worming and barren blights, complete with sample delves
terrain powers and hazards, skill challenges, companions, diseases, poisons, etc
Courts, Fair & Foul: 2 new Seelie and Unseelie courts, including court monster themes and Epic stat blocks of ruling monarchs
Flora and Fauna: 12 new fey plants and monsters
Faerie Shine: Alternative and magical rewards
Lore: Small, flavorful anecdotes related to Faerie
Health Resources: Register family with 911 services, so providers will have info prior to emergency/disaster. Also mental health info & hotlines, articles, treatment assistance options, prescription assistance, special needs registries, legal aid, and more!
