I created this world after a crash that deleted the original one my friends and I were working on. Due to a lack of time, we haven't finished a lot of buildings.
There is a functioning Iron Golem Farm, but it needs to be expanded. Also, in the jungle near that farm, there is a finished Zombie XP Farm.
The Nether is quite dangerous because we destroyed the old tunnels that connected our three bases, in order to make a new railway system. One of these tunnels ends in a portal to the desert. There you will find a Skeleton Farm. Another path leads to a Nether Fortress.
P.S.: Please excuse my poor english, for it is not my first language.
