I am developing a trade city, to supply the building of an impressive fortress in the mountains to the North. City currently features several types of farms and mob traps, and an ever expanding mine out in the desert. The goal is to generate everything the villagers like to trade. Take a minecart to the mountain base for brewing and enchanting, as well as the nether portal. In the nether you'll find a fortress with a blaze grinder.
Update: Added two large, self-harvesting farms. And, the chicken shack! Full of glitchy, chickeny goodness.
