On an endless sea, mankind lives aboard vessels wrought of leviathan bone and hide. They worship the stars and the barbaric deities of the sea. They build their cities atop the immense bones of slain monsters, or within the shelter of a leviathan’s cavernous carcass, where the remains of strange spirits can whisper long lost songs into their dreams.

Elementals of the air and the water are dangerous and capricious and harnessing them is an invaluable profession. Elementals of earth and fire seem to be man’s only friend in nature, if only because they long ago yielded to the dominion of the other two.

Beneath the surface, the remains of ancient civilizations still ghoulishly twitch. Scavengers, scholars, and seers all find their livelyhood in these ruins, but one wrong move can unleash strange, often incomprehensible dangers.

God-like leviathans inhabit the deeps and, some say, the spaces between the stars. They spawn cults, and rituals. They ask for bloody sacrifices. Religions rise and fall with the ages. Still, there are tales of beings from the ancient world who can still teach a man the old ways.

Life is hard on the waves, harder still knowing that the ancient stories say it was not always so. Once, the lands were whole and the seas were teeming and warm. A man could speak with his gods face-to-face.

Then, one day, men and their ancient gods delved too deep, sought forbidden knowledge and unleashed something terrible. The lands broke, the world flooded. Man’s intellect dimmed and his body changed, taking on monstrous shapes and appetites. His gods went mad. Now, all is obscured and paradise is no more.
