Once, the world of Verrilan was lush, with beautiful seas and vast continents peopled with colorful civilizations… And then, came the Fog. No one knew what it was. No one knew where it came from. But in less than a decade it covered the land, killing most it encountered and driving the rest to bloodthirsty madness. Civilization was forced to flee to the Floating Islands, situated high above, and pray to their gods that it would be enough to deliver them. 10,000 years have passed. The Fog still roils below, ever present as it blots out the land and the seas, its threat never truly forgotten. Yet civilization carries on in the Floating Islands with the help of the Sky Ships, steam powered marvels that much resemble the great seafaring vessels of old.
