Eluthan was an ancient walled city on the planet Acherin, built on a plateau. It was known for its strength as well as its beauty. The city was built with gray, blue, and bronze stones that awed many who looked upon it for the first time.
Over the next year after the Clone Wars, Eluthan was used as a base by those who resisted against the rule of the Galactic Empire. However after nearly a year of fighting, the Empire was too strong. The leader of the resistance, Toma, informed the Imperial Admiral Riwwel of their surrender, but Riwwel wouldn't hear it, and he ordered the bombing of the ancient and sacred city. It was left in ruins, leaving its citizens to squabble between themselves and the neighboring city of Sood.
