Talk:Twin-bladed Knife/@comment-29735342-20170918215022/@comment-1500935-20170920201702

The knife was recovered in Dunwall following the events of The Corroded Man and somehow sent to Karnaca to the Eyeless. Daud was chasing after it and got captured, his powers suppressed by music box-ish technology.

It's possible the original cult originally hid the knife in Tyvia believing no one would ever find it. They had no other choice but to secure it in Dolores's bank when it reappeared, because even some of the cultists were untrustworthy.
