Great Ayre Reach

"Amid the violent seas that had long since become the exclusive home of humankind, it was one of a few paradises worth dying for, one of the few pockets of peace close to the forbidding surface of the Imbrium Ocean."

The Great Ayre Reach is contested territory located between the Imbrian Empire of Nocht and the Republic of Alayze.

Characteristics
The Great Ayre Reach is described as a unique territory due to being one of the few places where the ocean floor is located in the photic zone, the surface layer of the ocean that is able to receive sunlight. Currents in the Reach are unusually gentle, and Leviathan activity is consistently low. This makes it an ideal territory in which to grow food or construct habitation stations, and as such it has been fought over by the Empire and the Republic for hundreds of years.

In the Story
Unjust Depths opens with a description of a battle in the Reach in which Imperial forces, led by Eric von Fueller, defeat a Republic fleet and temporarily assume control of the Reach.
