Bag of Portals

A backpack that seems to be able to open a portal to a mysterious storehouse. Looking inside reveals a spacious room with a single window. Outside the window appears to be a endless void. There is only one thing in the bag to begin with, a golem that seems to have one directive, organize any items put inside. The entrance of the bag can shrink any object or being so they can fit inside of the opening. Creatures inside become static, pausing all types of damages and not having to breathe, eat, or drink. As soon as they leave the bag, the static affect goes away, leaving them in the condition they were when they entered. While inside, fighting literally can’t happen, any action with hostile intent freezes the person.
