WARFRAME Wiki

If there are new discoveries to make or ancient tools of war yet to be excavated, the Grineer want to be there first — at the frontier of space exploration. Always seeking the upper-hand against their foes, they have numerous deployments that border the known reaches of our solar system, poised to enter brave new territory and unexplored space on command.
—Sedna Fragment

Sedna is a dwarf planet where the IconGrineerOn Grineer are the controlling faction.

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

The Assassination Target on this dwarf planet is Kela De Thaym, who is located in the mission node Merrow and where the blueprints for the parts of the SarynIcon272 Saryn Warframe can be obtained. Uniquely, in order to access the Kela De Thaym boss battle, players must accumulate sufficient Judgement Points by playing the various Arena missions on Sedna. As of Update 20.0 (2017-03-24), 25 Judgement Points are required to access the boss battle, with 12 being expended each time a player is successful in defeating Kela De Thaym.

Sedna does not currently have a Tenno Relay.

Notes[]

  • Due to Sedna being the second planet to feature the Grineer Shipyard tileset, it is also the only planet besides Ceres where Grineer Drudge non-combatants can be encountered. These are non-hostile until they are attacked and damaged, in which case they will attack with their various tools.
  • Due to the Grineer Shipyard tileset, this is also the second location beside Ceres where Guardsmen and their Eximus variant, the Prosecutors can be found.
