Pairing: Byakuya/Ryuuken, Aizen/Ryuuken, Aizen/Byakuya, implied Isshin/Ryuuken and Szayel/Uryuu.
Warnings: Dark, dub-con, emotional duress.
Summary: Taken. Suffering. Aizen's. Yet Ryuuken's pride remains indomitable. That is until Aizen introduces a third party into their twisted routine.
Notes: Kindofish sequel to As the Pillar Crumbles. It is not necessary to read both to understand either.
( Whatever their circumstances, they would not become a weakness for each other. )
