Underground Shops is a written note found in Dishonored 2.
Listen, I'm sorry we fought. I get what you're saying about tangling with the Howlers, but they don't run the black market here, really. They just take a cut from all the shops. Yeah, the Grand Guard will crack our heads or shake us down if we get caught, but they'll do that no matter what we do.
We're new here, and we picked a bad time to move to Karnaca. We've got to do whatever we can to stay afloat, even if it means dealing with the black market. So I'm going to find the shop in each district across this rotting corpse of a city, and I'm going to get to know the shopkeepers. Butter 'em up.
You're still my love, my apple, even when I yell at you. Even when I curse and throw things. I'll let you make it up to me when I get home tonight.
