Delilah on Rune Harmony is a written note found in Dishonored 2.
I've got all the ingredients ready in the Chapel. Dried kelp and algae from the moats. Flowers from the greenhouse, ground to dust and made into pigment. Human bones infused with the fluids of terror and regret!
Mustering patience, I will continue painting until the final rune is ready to affix to the throne. My throne.
But harmony must be maintained between the corrupt runes and their pure counterparts! Two corrupt, aligned with two of the purest. If this harmony is not observed, the magic of the painting could get twisted around and fail, or even turn against me.
