THE CYRO SEA
The Cyro Sea is a partially frozen mass of water north of Phildeterre. It is known mainly as the source of the Cylan River, which flows through the middle of the country.
Most merchants avoid the parts further inland of the Cyro Sea due to the danger of misleading icebergs, which form in the shallower water, and instead sail north of it where the water is warmer.
Though there are many areas with thick sheets of ice, walking on the Cyro Sea is not recommended, and many lives have been lost from thinner ice breaking under foot.
