Saya's Vigil
In the past, Saya was a close friend to both Onkko and Konzu, whom she married the former after rejecting the latter. The marriage did not last for long, as five years ago, during Konzu and Onkko's excursion out in the Plains, the latter mysteriously disappeared leaving Saya to mourn her loss.

Five years later, Konzu have heard of The Quills catching wind of the Grineer finding leads to Onkko, which prompts him to ask a favor for the Tenno to watch over Saya, fearing she may act recklessly. Initially, Saya blamed Konzu for his disappearance, reciting the elder man's motive being his rejected marriage proposal for the elderly woman, along with his iron flower. Eventually however, as the Tenno discover more clues about Onkko's reserach, she came into terms with his death and eventually came to accept Konzu once more after discovering his iron flower once again, which was kept safe inside Onkko's case all along.
