Shadowfell

The Shadowfell is a dark reflection of the Prime Material plane. While the topography is the same as the world of Elara, the shadowfell is covered in bones, roaming undead, shattered mountains, constant mist and neverending grey skies. Home of the Shadar-Kai, a dark negative reflection of elves, this is a place where much of the necromantic magic in the world originates. There is a known permanent portal to the Shadowfell in Vostergoetland, guarded by a singular mountain, and a shapeshifted dragon guardian.
