Out of nowhere, you all hear a dull roar from further into the cave. The sound grows louder until, in a matter of seconds, a massive surge of rushing water comes barreling down the passage. Everyone make a strength saving throw to hold yourselves in place.
Elora holds onto the cave walls, standing firm against the water.Cinder and Gorne barely manage to hold on against the raging current. Klarth and Vidar, you are both swept away in the current. The two of you are pushed out to the entrance of the cave, and take 1 bludgeoning damage as the waters toss you around.
The goblin tries fleeing back into the tunnel, but Cinder's fire bolt knocks it to the ground, where it lies still. Elora, Gorne, and Cinder stand in darkness for a few moments until Klarth and Vidar return, the light of Vidar's sword illuminating the passage. You are all soaking wet, but relatively unharmed. You can see about 20 feet further down the path before the eastward bend becomes too steep to see beyond.
