Time allotted to fate is dwindling.
On the predestined timeline, Ravenna's moment of becoming a hero, her transformation and elevation, were all erased by Ansel.
Beginning three years ago, with the forceful prolongation of the Tower of Babel's existence using firearms, to the present precarious situation where the Tower stands on the brink of collapse, Ansel ingeniously wrested it from the dangerous clutches of Evora. Elevating it further, he has now secured its position, ensuring a bright and stable future. Ravenna has lost any possibility of leaving the Tower of Babel.
She will forever be shackled within this lofty tower, her cold, rational willingness to sacrifice everything for her ideals remains uncorrected and perfectly exploitable by Ansel.
