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.
As a Syndicate, the Ostrons have their own Standing that can be exchanged for various rewards from the town's NPCs. Ostron Standing can be gained by performing various tasks for the Cetus villagers, such as completing Bounties and donating various items to them including fish and gems. The Ostrons are a neutral Syndicate, and gaining Standing with them will not affect a player's Standing with any other Syndicate.

TriviaEdit
- The syndicate faction was originally named Cetus after their village in preview builds, before being changed on release to Ostron, the name of their people in Update 22.0.
- Occasionally, a Corpus cargo ship will land on the docks or leave them, in the shadow of the Orokin tower. Pre-release streams showed the presence of Corpus Crewmen in the markets, abiding by a cease-fire, but their presence seems to have been removed as of release.
- As of the release of Fortuna, there are now once again Corpus Crewmen hanging around Cetus, as well as some Solaris that have set up a stall.
- The blade that Hok can be seen wielding cannot actually be crafted by the player, because it is missing a required link component.
- The Ostrons are featured in WARFRAME: Ghouls comic series.
- After a Tenno reaches the rank of Trusted with the Ostrons, NPCs will adopt a much friendlier and revering manners towards the Tenno.
