Having your own place is really important. It gives you somewhere to call /home, and means your items are much safer than leaving them out in the Wilderness. Sometimes, you might want a whole lot more space - that's where this package comes in.
This package grants you four extra claim chunks (16 x 16 areas) in addition to your starting chunks.
Personal chunk loaders keep a single chunk loaded into memory, even when you're not standing in that particular chunk. To activate a loader, place an Iron Block inside the chunk you want to keep loaded, and right-click it with a Blaze Rod.
These can be hugely beneficial when you want to spread your base out further than a few chunks, but also want machines to keep running when you aren't close to them.
Note that these loaders do not remain active when you log off.
