Small, distant Alsages is a small terrestrial, with a trace atmosphere of methane and argon. The surface is comprised of water ice and calcium with occasional deposits of light metals.
During the Alliance's pirate suppression campaign in the 2160's, the batarian Eluam Ran'perah was caught with his frigate Tunerron grounded on Alsages for drive discharge. When challenged by the cruiser Hyderabad, Ran'perah refused to surrender. The Tunerron was destroyed attempting to take off. The debris is strewn across the southern hemisphere.
