In this instance, the young people involved are focused only on what concerns them, which happens to be the "Summerlands" area. A full-blooded fey teams up with a human (who's slowly becoming fey) to find the witch, sorcerer or whomever stole the fey's magic. They set out crossing the land in search of someone who can give them information, but they don't venture into the world of the dark fey or swart elves.I'm coming at this as not a major reader of fae stories but I am familiar and have read some stories set in such realms.
How is your world set up? Are there different "factions" or are the various areas specific to the seasons?
I know the Scottish version is called Elfhame, but everyone's read about the Summerlands or Elfhame, hence the need for a fresh name. The story's about the characters rather than the realm so I don't suppose it really matters. LOL
