Ethras was an ancient city state on Arbre, situtated by the Sea of Seas.
In 2621 the Temple of Orithena was destroyed by volcanic eruption, beginning the Peregrin period. Many surviving theors move to Ethras. This contributed to the Golden age of Ethras, which lasted from -2600 to -2300. During this period, Ethras was home to Thelenes, Protas, and many other lumininaries.
In -2272 Ethras forcibly absorbed into Bazian Empire.
Ehtras is the Arbre version of Athens.
