May contain plot details
Elfhame is the main setting of The Folk of the Air series
Queen Mab’s crown was magically and wondrously wrought so that it passes only from one blood relation to another in an unbroken line. With the crown passes the oaths of all those sworn to it, although her subjects gather at each new coronation to renew their fealty. The authority still rests in the crown.
This makes it difficult to take the throne of Elfhame by force. A condition of the crown was that there must be two royal children when a coronation takes place, one to crown and one to be crowned. Only when there are less than two descendants of Mab's line will the crown be broken.
Elfhame is made up of four islands. Insmire, Insear and Insweal create an outer circle with Insmoor in the middle. All three islands are connected by half-submerged rocky paths and stones large enough that it's possible to leap your way from one to the next. Insmire contains the Palace of Elfhame, Madoc's Stronghold and Hollow Hall. Insmire is where most of the inhabitants of Elfhame live. Originally, Elfhame was made up of only three islands (Insmire, Insweal and Insmoor) until King Cardan created the fourth island, Insear.
- Elfhame and its High Court were first referenced in Holly Black's 2002 novel Tithe: A Modern Faerie Tale.
