Servicing the Windmill is a written note found in Dishonored 2.
Transcript[]
Corporal Ritello,
if that engineer comes back to service the windmill, do not go up the ladder to throw the shut-off lever for her. It's not your job and I won't have my squads taking risks like that for another department. They're not Grand Guard.
If the lead engineer is afraid of heights, it's her problem. How she expects to work on the windmills, without being able to climb up to the shut-off, I have no idea, but I don't care.
- Captain Figuera
