You're out of the book.
I decided awhile back, that for in-game and story reasons I had to cut out Fey.
I know, it's sad. The Fey still used to exist, but they're dead now. There essence has been smashed down into a magically reactive mineral known scientifically as Arcanite.
That's what happens when Celestial Planes collapse, people die, and those people are fey. and elves. because elves are fey-ish mortals.
Happy St. Patrick's Day
