Even the most culturally and technologically advanced civilization in history could not contain the menace of the Infestation. After an unknown cataclysmic event propelled them from the Void, Orokin vessels were left adrift, becoming uninhabited and overgrown. The tireless force of probing infested tendrils penetrate and dislodge the once majestic and opulent halls of these Orokin vessels.

—Derelict Fragment

Deimos is a moon of Mars where the  Infested are the controlling faction. This Infested-controlled moon uses a tileset similar to the Orokin Towers, called Orokin Derelict, taking place on ancient Orokin vessels that are left abandoned to tides of time and tarnished due to long-term exposure to the Infestation. The caverns beneath the moon's surface are home to an Orokin device known as the Heart, the legacy of the Entrati family which establishes a connection to the Void to power all Orokin Void technology across the Sol System. The Heart of Deimos quest implies that Deimos was previously concealed in the Void, having recently re-phased into Martian orbit after the Heart begun to break down.

Deimos becomes accessible after clearing Kadesh, Mars, and does not have a Junction.

The Assassination Targets for Deimos are Lephantis and the Zealoid Prelate, located in the mission nodes Magnacidium and Exequias respectively. Lephantis drops the component blueprints for the parts of the  Nekros Warframe, and The Zealoid Prelate drops the blueprint and parts for the  Pathocyst.

Deimos also features a Landscape: the Cambion Drift. Unlike the Derelicts, it consists of a wide, open terrain on the surface of the moon heavily mutated by the Infestation's Grey Strain. In the northeast lies a large structure home to the Entrati family, now known as the Necralisk.

Orokin Vault

Main article: Orokin Vault

The Orokin Vaults, also known as Dragon Key Vaults and "The Golden Door" by the Ostrons, are special vaults found in the Orokin Derelict tileset on Deimos missions which require a unique void key to unlock, called a Dragon Key.

Corrupted Mods

Main article: Category:Corrupted Mods

Corrupted Mods are a class of rare mods that affect one stat beneficially (a bonus) and another one detrimentally (a penalty). Those available for Warframes are characterized by extremely high bonuses outweighed by major penalties. Those available for weapons provide bonuses of a similar strength to their standard mod analogues, while still also having a penalty. Corrupted mods can be obtained from the Orokin Derelict using special Dragon Keys to unlock Orokin Vaults located within. They are untransmutable. Visually, they do not have any special distinguishing mark and appear as any other mod of Rare rarity (i.e. gold-colored).

• Corrupted mods that provide a bonus to Critical Chance (e.g.  Critical Delay) are a notable exception to the general pattern of nonstandard mods in that they cannot be stacked with their standard analogues.
• There are currently 23 Corrupted Mods and each of them has an equal chance to drop (4.3478%).

Tips

• Deimos is the first location in the Star Chart where  Orokin Cells can be found, making it a good place where to farm them due to the low level of enemies in the first missions.

Trivia

• Deimos, which in Ancient Greek means Dread, is named after the Greek God of Terror who is also the twin brother of Phobos.
  • Befitting of its name, the moon as a whole resembles a large skull with its lower jaw hanging open.
• Mission Nodes on Deimos are usually named after fear, death, and suffering.
  • Phlegyas in Greek mythology is the son of Ares and Chryse and therefore a sibling of Deimos. Its etymological root is in the greek verb flego which means to shine, to burn, to blaze.
  • Formido is the Roman equivalent to Deimos.
  • Hyf in Old English roughly translates to (bee)hive and in Swedish it refers to the long, threadlike filaments that form the mycelium of a fungus.
  • Dirus is a Latin word that means "fearful" or "ominous".
  • Horend is a form of the word Horrendous.
  • Terrorem means terror.
  • Exequias is a Spanish (coming from latin exequiae-arum) word that translates to Funeral (rights).
  • Magnacidium may be a portmanteau of the Latin words Magna (from the word Magnus, meaning "Large" and "Great") and the suffix -cidium (meaning "slaughter" and "act of killing").
• It is implied that Deimos, much like Lua, was hidden within the Void until recently in the game's timeline, as Loid mentions in Heart of Deimos that they "have been forced to re-phase into Martian [orbit]" before being interrupted by Otak as well as the quest's description saying "Deimos emerges in Martian orbit".
• Interestingly, Deimos and Eris are the only planets of the Star Chart that were not seemingly affected by Narmer during the New War.
