Edolus is a terrestrial planet with an atmosphere of carbon dioxide and nitrogen. Edolus's surface is covered by wide deserts of silicate sand, with only a few areas of igneous rock highlands to break the abrasive, dust-choked wind.
Edolus's orbit is congested with debris thrown inwards by the gravity of the gas giant Ontamalca. Due to a high rate of meteor impacts, exploration is highly dangerous.
- Note: The Mako can land here. The Planet has Palladium, Polonium, and Lithium deposits. There is a crashed probe which can be salvaged. A Salarian ID tag can be found here (for UNC: Locate Signs of Battle). There is a Thresher Maw on this world with some missing marines (for UNC: Missing Marines).
