The Dream of Brine

Again with the dream. I see River's Bend laying before me, the farmland and river nestled in the deep woods. Warm and welcoming, but my eye is drawn north and there among the Icespire Peaks do I feel the beast. A cold and omnipresent weight bearing relentlessly until a dam breaks and from the mountains comes a deluge of ice and water raging forth to flood my home and then the world.
 
An unnerving dream to be sure and so I went for a swim to wash away any bad energy that may still be cleaved to me. Yet every wave crash seemed to be carrying the voice in an ever sterner tone stating "Release me".
 
I must double down on the studies and solve this riddle.
