Ryuken and Isshin are both in the Seireitei, or at least what is left of it after Yhwach fused it with the Wandenreich. They look around. The sky is red above all the western style buildings; white, imposing, and covered in ice. The main battles of the war have already been fought. Everything that needed to take place between the Soul King and Yhwach in the Soul Palace has already taken place. Now is the time for killing leftovers, saving civilians, rendering medical aid.

Ryuken and Isshin look around the wreckage, exhausted yet determined. In the middle of the city they see the Silbern Palace with its sharp overhanging crescents coated in icicles. Their task is to empty that building and dispose of any remaining Soldat.

As they enter, they see a woman, deathly injured in the foyer. She is obviously a Quincy, yet not a Soldier. Upon further observation she is a maid of some kind. She coughs up blood as they approach.

She looks up at them, particularly focusing on Ryuken in his all white Quincy Sternritter uniform and spouts a sincerely shocking thing before she collapses and dies,

"Save her... save... save the Echt woman... She is... she's the only one left... the-the key... it's... in my hand... please... she'll die trapped... in that cage..."

an Echt.... a female pureblood of all things... how is that possible....
