The Astral Sea

The vast stretch of open space that separates the four plates of Simuhay. While there are small islands dotted throughout - some of which are just large enough to have their own small atmospheres and biomes - the Astral Sea is largely empty. Due to this, traversal through the Astral Sea is extremely difficult. It is possible to hop between the sparse islands, but larger scale travel requires a flying vessel of some sort. Despite this, there are still a few major places of note within it.

Interestingly, the Astral Sea’s presence as a divider between the plates was not always a given. A long time ago, the four plates used to be connected to each other and the Astral Sea only surrounded Simuhay’s outer border. The events of the Mana’s Ascension led to the shattering of the world that split it into the plates, which subsequently drifted apart, allowing the Astral Sea to fill the spaces between.
