Kaeros Isle was once a beautiful tropical paradise due to the warm ocean current. The forests were dense and loaded with fruits during the growing season. Farmers would harvest exotic fruits and vegetables and sell them for lucrative prices across the continent. This quickly changed about 120 years ago though when the top of the mountain blew off, spewing tons of ash and dirt into the atmosphere. The inhabitants of the island were killed almost instantly from the explosion and the entire continent felt the effects as the ash and dirt caused 30 years of darkness and winter.
This event ultimately triggered the War of Dust.
