The Great Disasters
In the legends of The Gaflaptha Religion, there were two great disasters before the current plagues.
In the first age, Bachda, Goddess of Fire, taught the humans how to make fire by putting a Yan, or soul, into a hearth. This angered the other gods into sending floods, earthquakes, storms, and other elemental disasters.
In the second age, Miiran, Goddess of Light, taught the humans magic by breathing a yan into a word. The humans misused the power, and all eight gods cursed the world with a long period of darkness and cold.
The legend states that there will be five more ages, before Luuda returns the earth into the sea, ending the cycle of ages.
