|“||Even the very air of Dark Aether is dangerous, and can cripple the strongest of warriors.||„|
The air of Dark Aether is the primary danger posed to offworld entities in the dark version of Aether. Any being exposed to its harmful effects will quickly begin to burn away, unless they possess a form of protection against it, or are born of Dark Aether. The atmosphere seems to contain elements of Dark Energy.
Samus Aran's Varia Suit provides limited protection from the effects of the atmosphere. When exposed, the Varia Suit takes high amounts of damage, losing five units of energy per second, and makes a fizzing sound. The HUD will periodically flash in a faint yellow and the Threat Assessment meter will immediately reach its highest level unless Samus seeks shelter in Light Beacons or Crystals that are placed throughout Dark Aether, which negate the harmful effects of the air within their field. Once acquired, the Dark Suit will reduce damage to Samus from the atmosphere, and she only loses one unit of energy per second (the HUD will no longer flash yellow and the fizzing effects are also reduced). The Luminoth-designed Light Suit is the only upgrade capable of making Samus completely immune to the air, as it contains the Light of Aether.
In Metroid Prime: Episode of Aether, Samus states that the atmosphere is filled with "poisonous gas".
