Eletania

Mass Effect
WARNING: Level 1 Toxic Hazard

Eletania appears to be a world eminently suited for colonization. Sadly, appearances are deceiving. It is covered by a verdant carpet of mosses, algae, and lichen, and possesses a thick oxygenated atmosphere, but the animal kingdom is a web of microscopic symbiotic creatures. These are impossible to filter from the air and necessary for the native life to thrive. Unfortunately, they also cause anaphylactic shock when inhaled by non-native life.

In short, settlement requires either fully sealed environment suits, or replacement of the entire world's ecosystem. Some have proposed limited colonization at altitude above the symbiots' range, or in areas where favorable winds keep the air clear.


 * Note: The Mako can land here. There is a Prothean ruin that can be investigated using the trinket you obtained from the Asari Consort. There is a crashed probe that can be salvaged here. There is a downed probe for UNC: Lost Module here.

Eletania appears to be a world eminently suited for colonization: It is covered by a verdant carpet of mosses, algae, and lichen, and possesses a thick oxygenated atmosphere. However, its animal kingdom is a web of microscopic symbiotic creatures that are both impossible to filter from the air and necessary for the native life to thrive. Unfortunately, they cause anaphylactic shock when inhaled by nonnative life-forms. Settlement by nonnative species would require either fully sealed environment suits, or a replacement of the entire planet's ecosystem. Limited colonization has been proposed for altitudes above the organisms' range, or in areas where favorable winds keep the air clear.
