Minecraft wiki entry for Building_a_metropolis, associated text: Magic City: Place brewing stands, cauldrons, and enchantment tables in abundance around the city. Magic cities can sell things like potions, potion ingredients, enchantment tables, brewing stands, cauldrons, enchanted books and armour, and bottles o' enchanting. Using ender chests instead of regular chests adds to the effect. Use witches, evokers and illusioners for inhabitants on singleplayer for fun, but they are likely kill you in Survival. Build multiple Nether portals and possibly expand the city into other dimensions.
