Arawn's Forge
Arawn's Forge is a Stable Point of the Far Dreaming.
Overview

There's a solitary mountain, black as a fomorian's heart, where once Arawn held his court. The sides of the mountain are as slick as wet glass and the winds howling around the peaks prevent even dragons from flying close enough to land. The air is bitter cold, and a thick frost rime covers the surrounding lands. But in the darkness of night, there comes a glow from the center of the mountain that spills forth from a deep pit at the very pinnacle, countless leagues above the ground. The glow is bright enough to turn the bottoms of the clouds that always surround the loathsome place a bloody red.
Here, the Thallain believe, Arawn once devised great weapons of darkness, preparing for a time when Winter's embrace would be needed to stop the Tuatha de Danaan and the Seelie Court. The Shadow Court wants the weapons they believe wait in the bowels of the mountain. With those weapons, they remain convinced that Winter can be brought forth and, someday, Spring's return hastened.
The whispered legends say only the bravest and purest heart can ever reach the top of the mountain. Only the noblest can claim the crown of Arawn and the black sword called Winter's Heart. Although they've had no success, the Thallain still seek the one who can scale Arawn's Forge and bring them the weapons of their destiny.
