Cetus and the Plains of Eidolon
The market where the Ostron live beneath the Tower of the Unum, and the plain roamed by shattered Sentient Eidolons.
EARTH · OSTRONLIGHT SPOILERS
Ostron life
Fishing, mining, the market and family ties build an everyday culture in the middle of a war. The standing relationship turns the Tenno from an outside warrior into a friend of the community.
The Unum
The Tower gives the Ostron flesh and protection, and shows a limited foresight about time and possibility. Its full nature has never been openly explained.
The Eidolon night
The fragments of a great Sentient search for the whole they lost. Operator Amp power and partnership with a Warframe are the narrative foundation of the Eidolon hunt.
