In the Crimson Hills, the Fae of New England.
Four of the Lost have recently come through the Hedge from Arcadia, and found themselves in the Northeast. The local freehold is known as the Crimson Hills, and is located just south of Boston, in what the mundanes knows as the Blue Hills Reservation. This reservation is not quite what we know it as. It has no trails which lead into it, and was set off as a reserve only politically as "a nature conservation area," and the reality is that it was set off as a warning – "here there be dragons" is what it might be labelled on an old map. It is, in fact, inhabited by Fae.
The Lost of the northeast, commonly known as the fae of New England, despite New York's outlier status, are organized into a loose federation. There are four main freeholds which are in the federation – The Crimson Hills of Boston, the Emerald Island of New York City, the Ashen Bay of Providence, and the Onyx Mills of Manchester, NH. The four are pledged not to the common defense, but rather to the common non-agression. There are matters sometimes of trade and bargaining, but very few actual rules between them. This system was agreed upon in the terms of the Treaty of Vernon, an original neutral meeting ground in Connecticut. Each freehold is loosely aligned with a season according to this treaty, with the four freeholds of Boston, NYC, Providence, and Manchester being Summer, Spring, Fall, and Winter respectively. This does not point to their total numbers of fae relative to each area, or to general dispositions, but is mostly an administrative designation – mostly.
