While I defer to my friends at the wiki and Mr.@TheEdVerse, I would add Evermeet to the list. The isle of elves existed within the Feywild for over a century before returning to Faerun/Toril during the Second Sundering. Ah. You see, in my mind Evermeet isn't part of the continent of Faerun, so was off the table as the question was framed.
