D&D Random Encounters for 5E - Underwater
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.
Encounters underwater bring visions of murky seas, vast reefs and dark depths. They might occur in a kelp bed, an underwater cave or by a long-forgotten shipwreck
