Hallowed Briar
The Kingdom of Hallowed Briar, the Kingdom embodying Dark Magic. The Hallowed Briar is the easiest to wander into, as it is accessible by taking a "wrong turn" when trying to venture into any Faerie Kingdom. Though it harbors and upholds dark magic, it is far from an evil place.
The trees here are always autumnal or dead, and much of the foliage here is poisonous or otherwise unsafe to consume without cooking- though the population have even found a way to distill arsenic into a delicious beverage!
The Hallowed Briar is also the epicenter of the Faerie holiday Parade Macabre, a weeklong celebration ending on the Winter Solstice celebrating fear, death, and being together and familial through such.
Magical Anchor of Death Magic. Home to a LOT of undead mad scientists.
The Hallowed Briar's "nightlife" hotspot, full of all sorts of delightful dealings and representing the areas where Indulgence Magic and Dark Magic meld together.
The magical heart of the Hallowed Briar- where the spine chilling horror shows put on here keep the Kingdom- and Dark Magic- alive.
