Sometime in the late Merethic Era, specifically during The Return, a violent storm (later named Storm of Separation) took place at sea. This was the event that ultimately led to the death of one of Ysgramor's sons, Yngol.
As time progressed, however, the waters became extremely icy and Atmora froze. The icebergs that litter the water have claimed several ships over the years.
