Many questions remain: What is the true history of Cetus? Who is the Unum and for how long has she been one with the living Tower? What is her relationship to the Quills and what hidden purpose do they serve? The Archivist, Onkko, preserved much of the old folklore, but how much of that is true?
If there is any kind of scheme to the unfolding of things, some end-point in sight, then one thing is certain: the arrival of the Tenno in Cetus is no accident.
