Private Dimension is based on the Spectre Key from Random things!
It adds a key that teleports you to a custom room in a private dimension! You can increase the size of the room by giving items to the core in the center of the room (Default item is Nether Star and some fictional items, but you can add as many as you want to the list!)
A complete config file that allows to config how the size is increased, what the base size is, what items can be used to increase the size, etc. The best part is that you can add items from other mods to the list too!
Use the key while in the dimension to go back to your EXACT previous location!
Here is a video showing off the basic features of the mod!
