Corvo's mask, the result of one of Piero's dreams.
Piero's Dark Dreams is an audiograph found in Dishonored, recorded by Piero Joplin.
Transcript
The inspiration is coming faster. My mind works faster at night than it does during the day. I'm being swept away, and I can no longer tell if it's genius or madness. When Corvo arrived, he brought some force from the Void with him. Or perhaps I am more brilliant than even I had supposed.
Location
The audiograph can be found on the table to the left of the main entrance to Piero's Workshop after the mission High Overseer Campbell.
Trivia
- Piero's spoken final sentence differs from the transcript in that he does not say "had".
