The Atharian Republic formed early in the first millennium following the First Devastation, and became the greatest of the human empires. Around 600 AD it started to be ruled by a single Emperor, and controlled most of Eyressia.

By the Second Devastation, it's trade routes collapsed and unable to pay its armies it pretty much collapsed, holding onto some lands around the capital of Athar itself.

By around 1300 AD, it had begun to rebuild itself, but suffered a catastrophe when the city of Athar was struck by the Blight. The capital moved to Tannos, and shortly after the senate took full control, returning Atharia back to being a Republic.

Now it controls lands around the Middle Sea.
