Cetus is a village built by the Ostrons, located to the north of Mantle, Earth. A humble settlement, located in the south region of the Plains of Eidolon, they are guided by a secretive order named The Quills, loyal to the ever-mysterious Unum, who constantly watches over the plains keeping her people safe from Grineer aggression.
As a city hub, players can interact with various NPCs to purchase items from shops, or accept quests or bounties to be completed out in the plains. Players can enter the plains via a large Orokin door on the town's outer wall, leading to a large room which has another door that leads to the plains beyond. The room acts as a loading screen, and players will be unable to exit out the other end until the loading is complete.

The Ostrons are the inhabitants of the Cetus settlement near the Plains of Eidolon on Earth. They are a hardy, mercantile people that dwell in the shadow of the Orokin Tower of the Unum, which they harvest for their livelihood. Kept safe from Grineer aggression by the arcane powers of the Unum herself, Cetus serves as their central trading hub in the Origin System and a refuge for all others who come to it with peaceful intentions.
- Main article: The Quills
The Quills are a mysterious monastic order that serve the equally enigmatic Unum, a being who resides within the Orokin Tower at Cetus in the Plains of Eidolon. They have very close ties to the Ostron people who also praise the Unum, and are seemingly knowledgeable about the secrets of the Tenno. They are said to be able to divine the future, which combined with their information gathering prowess allows them to preemptively end threats to Cetus through their operatives.
Plains of Eidolon
- Main article: Plains of Eidolon
The Plains of Eidolon is an expansive, open Landscape connected to Cetus, an Ostron settlement located on Earth. In the shadow of the Orokin Tower of the Unum lies an ancient battlefield, where an enormous Sentient was defeated during the Old War by Gara. The Grineer have set up numerous outposts and bases to study and mine the ruins in the area, observing and patrolling the plains for any threat to their operations.
- In the eastern part of city outskirts hides an Easter Egg in the form of the Digital Extremes logo, easily recognizable by its emblem. Activating it will show the credits roster for the Plains of Eidolon.
- In the roster is Hayden Tenno, the main protagonist in Digital Extremes' previous game Dark Sector.
- Cetus is the Latinized form of κῆτος (ketos), the Ancient Greek word for "sea monster" or "huge fish", but in recent times, the word is associated with whales (i.e. cetaceans). Cetus can also refer to a constellation of the same name.
- Interestingly, one of the stars in the Cetus constellation is Tau Ceti, one of the closest stars to the Sun and is most likely the "Tau" system the Sentients were originally sent to colonize.
- Another interesting fact is that Eidolons vocalize using the calls of humpback whales, as seen in Devstream #102.
