D&D Random Encounters for 5E - Shadowfell

Encounters might be a meeting with a patrol of guards at an old shrine or a familiar looking for aid. It might be an ambush in the wilderness, a stand-off in the city or a monster in the Underdark.
The Shadowfell is a pale reflection of the world, a place of shifting shadows, twisted crystal trees, crumbling ruins and foul rivers. Meet cursed spirits, doomed cultists, hordes of undead and servants of the Raven Queen.
