Breanna Ashworth's Notes is a written note found in Dishonored 2.
The original lenses Jindosh and I devised for the Oraculum were horribly flawed. Rather than focusing the energies of the Void, the faulty lenses scattered them. My head was filled with noise and the spiritual channel linking me to Delilah's magic was nearly extinguished.
I will not cease my efforts until our Coven controls the Sisters of the Oracular Order. But I know now that I proceed at a grave risk. The old lenses could have been my ruin. They are stored in my workshop for now, but must be destroyed.
The note can be found in Ashworth's workshop during the mission The Royal Conservatory.
