Argai was a chilly rock world with little to see except scattered ruins and the blaze of the Indrexu Spiral in its night skies. The planet was the site of Xim the Despot's grandest palace, but became little more than scattered stones over the eons.[2]
The Argaians were renowned and cursed since the first days of the Tion Cluster history as hard-bitten traders and daring pilots with a habit of turning to piracy.[2]
Xim came to power on Argai in 25,130 BBY where he built one of his palaces.[3] He made Argai the capital of his empire and the site of the first of his throne worlds. He extended his domain from the Radama Void to the borders of Hutt Space. After Xim's death, his Empire broke into feuding states. Argai was integrated in the Jaminere Marches.[2]
The planet and the Tion Cluster eventually joined the Republic. In the Republic's final years, the Tion Cluster worlds joined the Separatists and were later members of the Galactic Empire.[2]
