Ostron

"A tight knit band of merchants, hucksters and survivors, the Ostrons call Cetus their home. The town was built around an Orokin Tower, that both protects and nourishes them."

Cetus is an Earth settlement built by the Ostron people in the shadow of an Orokin tower, which they dismantle and harvest for various usable parts. This town serves as the central hub for the Plains of Eidolon, where players can interact with various NPC's to purchase items from shops, or accept quests to be accomplished out in the plains.

As a Syndicate, Cetus has its own Standing that can be exchanged for various rewards from the town's NPC's. Cetus Standing can be gained by performing various tasks for the Ostrons, such as completing Bounties. Cetus is a neutral Syndicate, and gaining Standing with them will not affect a player's Standing with any other Syndicate.
