River Ruins (location/dungeon idea)

Appearance: It's a ruined building that descends downwards just under the ground, under ground rivers run though this place.

Backstory: These ruins use to belong to an ancient king, who controlled the rivers. The people & river creatures revolted, destroying his kingdom & this building.

Possible traps/obstacles: fast flowing rivers, falling architecture, ancient traps (ie floors that fall out & lead to spikes)
