As you walk to your villager trading hall, your eyes fall upon the various villagers. They look at you expectantly, waiting to be traded with. A blacksmith, a librarian, a farmer, a butcher, and a cartographer all stare back at you, ready to offer their respective goods and services. In this trading hall, the villagers work like slaves and you're their master, ready to trade them emeralds in exchange for their goods and services. They don't look very happy living in the tiny cells.
