There are lots of homebound fey spirits in mythology and folklore. Lots and lots and lots. Which makes sense; that's the most important place and most occupied place in everyone's life. But how do they translate into an RPG, which is (lets face it) generally about conflict?
There are a lot of ruins in D&D and similar games. And a lot of ruins in real life. Without modern building materials, buildings decayed and fell apart. Streams moved, families died out or went elsewhere. What happens to the fey of those places?
They go feral. Spriggan. Redcaps. Buckawn. Field fey that are left with gifts and a good-bye party might dwindle and become grig or pixies. Those abandoned become will-o-wisps.
Neutral or good fey might be domesticated or reclaimed if people return, but fey that have "gone sour" must be removed before a field or foundation may be reclaimed. And that is an adventure.
