The Dead Sea

Ocean

The center of the world drains & rises, crossing is dangerous but going around is slow.

A sea surrounded by continents, on a cycle almost predictable, 3 or 4 weeks at most, it drains. Little life survives within longer than a cycle. And when it returns, with storm and thunder, it takes from all which surrounds it. Crossing is dangerous but going around is slow.

An evergrowth born of a Great Tree, an infectious paradise for those within.

Mikiltré, the Living City is a paradise to many, growing & changing to house and feed those within. It's spores spreading, changing, and joining them.

In the Desert rises an oasis of marble and gardens, of euphoria for the privileged.

The Dominion has ever been a force upon the sands, where great houses drive daggers held by "indentured servants" into each other. Though they may live long, they do not live cheap.

The Lands of Ash

Continent?

The home of devils and demons.

Though it's location disputed, any true born devil or demon knows the way. An near inhospitable wasteland split between law and war, devouring itself. No wonder they seek escape.
