The Feywild

A land of wild magic and nature, overgrown and beautiful and super fucking dangerous. The gods rarely tread here, but keep an eye out just in case.
The major locations are the town of Iris, one of the more populated settlements of the feywild. Mostly inhabited by Eladrin and ran by The Ogdoad.
The major sea in the feywild is the Glass Sea, an ocean of shifting iridescent planes of glass. INCREDIBLY deadly, but beautiful.
