World Map from the view of the oceans.
Basic Key:
The largest areas are land masses.
From lightest to the next darkest: Levels of the sea bed (Brightwaters, Gloomwaters, Inkwaters, and Abyss) with a line between them.
The lines have a shorter line or arrow on them. Moving in the direction the line/arrow points takes you into a deeper section of water.
Translucent dash lines with arrows are major currents, showing the direction they flow. Used by the largest traveling communities to get around in their floating villages.
Large stars are major cities.
Half circles with a line curving over them are sea caves.
Dotted lines through land masses are known sea cave routes to get from one large body of water to another.
