The basic idea of this server is that players can buy a 500x500 world and invite their friends to it. However this world does not start out as 500x500. It is split into 100 50x50 chunks, and each new world starts with the 4 center ones. Players can then buy 50x50 expansions for their world (which mirrors a prebuilt world). Each world is considered a town, and only town members can visit it. This lets players sort of have their own lan world anywhere. There are also modules you can buy! These modules are of different resource facilities (farms, mines etc) They are a block you place down and then produce items every hour one of your town members is online. These items are placed in a trapped chest within the module. You can upgrade or remove a module by right clicking the sponge block within the module. You can then pick up that module and move it wherever you please!
