D&D 5E Encounter - Hill
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.
Hill terrain covers a range between farmed valleys, rugged moors and mountain foothills. Encounters can occur among mossy rocks, by a stone circle or in an abandoned hill fortress. Often between mountains and plains, civilisation and the wilds, they are the home of vigilant sentries, monstrous raiders and beasts domestic or wild.
