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 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 Saryn Warframe can be obtained. Uniquely, in order to access the Kela De Thaym boss battle, players must accumulate sufficient Judgment Points by playing the various Arena missions on Sedna. At present, 100 Judgment Points are required to access the boss battle, with 50 being expended each time a player is successful in defeating Kela De Thaym.

Sedna does not currently have a Tenno Relay.


Invasion Missions: The Corpus will appear as a "Sideable or Opposing" faction while the Infested will always appear as an "Opposing" faction during Invasion missions.
