Cetus fragments
This page lists the Cetus fragments found by scanning the Thousand-Year-Fish statuettes on the Plains of Eidolon. Each contains a hidden fragment of a story narrated by Cetus Archivist Onkko. The hidden story is listed last.
After finding all 20 fish statuettes, the Tenno will receive an inbox message from Onkko containing an Orbiter decoration of the Thousand-Year Fish.
Inbox message:
THE SEARCH IS OVERYou have searched long and hard to find all my fish. Yet, your success was always known. Will you discover the secrets within them, the layer hidden? To honour your achievement, the Quills bestow this statuette upon you.
