There are no longer any active military or research campaigns in the Eris region – it is overrun. Long evacuated Corpus and Grineer vessels drift aimlessly in orbit, slowly being devoured by the techno-organic parasite known as the “Infestation”. What remains is a twisted graveyard of partially-digested ships that are disfigured versions of their original forms... Abandoned, but not unoccupied.

— Eris Fragment

Eris is a dwarf planet overrun by the Infested. Prior to Update 14.0, the Corpus were the controlling faction.

Eris becomes accessible by defeating the Specter in the Eris Junction on Pluto after completing the required tasks.

Eris has two Assassination Targets: Mutalist Alad V, who can only be reached by crafting Mutalist Alad V Assassinate Keys with the blueprint awarded from the Patient Zero quest, and the Jordas Golem, who is unlocked after completion of the Jordas Precept quest. The parts of the Mesa Warframe can be obtained from Mutalist Alad V, while the Jordas Golem drops parts for the Atlas Warframe. Both bosses do not occupy existing nodes on the planet, instead having their own individual nodes appear once they are unlocked.

  • Eris is named after the Greek Goddess of Discord, owing to the fact that its discovery led to the debate and demotion of Pluto's status as a planet.
    • Many of the Eris's missions are shortened names of various diseases, parasites and fungi.
  • After The Hunt For Alad V Eris was the only planet left to be completely controlled by the Infested, but they were eventually replaced by the Corpus in Update 11.3, but the Infested regained control in Update 14.0.
    • Since Update 14, Eris remained populated solely by Infested until the addition of Spy 2.0 within Update 15.13 caused the Corpus Faction to now hold one node.
  • According to the Operation Oxium Espionage weekend event, the formulation for Oxium was rediscovered in a research facility near Eris.
  • Eris is the only planet that hosts the Hive Sabotage mission type.
  • Eris is the only planet to use the Infested Ship tileset for all nodes excluding Xini the Interception mission.
  • Eris also has the unique distinction of having two unique Assassination targets: Mutalist Alad V and the Jordas Golem, each occupying their own nodes and having their own unique missions. While Phobos was the first planet to have two Assassination targets with the team-up of Captain Vor and Lech Kril, unlike with Eris both bosses are found on the same mission, and the pair are considered a single Assassination target.
    • Interestingly, as Mutalist Alad V requires a key to access, and "The Jordas Golem Assassination" has the Jordas Precept as a prerequisite, unless the player has the components for Mutalist Alad V's key or the Jordas precept quest completed, there are no available assassination missions available on Eris.
    • The two individual boss-fights on Eris make it the first planet in the game on which two Warframes are dropped.
  • Until Hotfix 15.2.2, the Viver node was a Corpus Interception mission, making it the only non-Infested mission on the planet. This node was removed entirely in Update: Specters of the Rail.
  • Phorid originally was the boss of Eris, located in Naeglar until Update 11.0 when it was relocated to inhabit Invasion missions, and only when they reach the planet's boss node.
    • However, defeating Phorid still rewards the player with the Savior of Eris achievement.
  • Prior to the introduction of Mutalist Alad V in Update 15.5, Eris was the only planet without a Boss mission.
  • Prior to Update 11.0, Eris's (and Europa's) description read: "The Infested are spreading throughout the Orokin Derelicts in this region". This implied that at least some of the Orokin Derelicts are located here.

Patch History

Hotfix 19.5.6
  • Fixed "Find and defeat Lephantis in Orokin Derelict" Eris Junction task only completing if the Assassination Key was used to run the mission.
