Infinite Vessel

The Infinite Vessel is an on-demand rentable product, designed to be a body or extension for any given individual.

To use, the user must first rent the product to free it from its holding chamber. The hatch on the holding chamber will open, where the Infinite Vessel is then able to be controlled. One does not need any sort of magic knowledge to use this; it has virtually no threshold for strength, and as such, simply thinking of controlling it will allow the user to pilot it.

It functions much like a separate being, being nearly completely in sync with its current user. You barely even have to think about using it; it'll match its actions to your thoughts.
