Schrodinger Box

The Schrodinger Box is a ubiquitous and widespread technology throughout much of the Weave. Coming into existence during the first Aeon War, this device was designed to grant protections to the user against temporal threats such as time paradoxes and retroactive erasure. The device works only on beings bound to causality, as acausal entities don't need such protections.

Appearance
The Schrodinger Box is a shape and size shifting container, being made in a 'one size fits all' configuration.. When in use, the Schrodinger Box encases its user as a metallic sarcophagus.

Function
When a user enters the box, the device 'cuts' the personal timeline of the user up until they used the box, while preserving their current state of existence. This renders any attempts at killing or unmaking someone in their past completely ineffective. The process leaves behind a 'shade' in the user's past, who would perform all the actions that the user performed in the past, but in most cases cannot be affected. Destroying the shade does not cause negative consequences to occur to the user, as the present existence of the user is separated from their past.

A highly illegal modification of the device allows the creation of 'Shifts'. Volunteers, or just as often victims, undergo a modified process to become a Shift. The being that uses this process becomes completely disembodied, reduced to a self-aware collection of ideas or concepts that once comprised them. This mix of ideas and concepts can freely travel the multiverse, and affect the minds of those who perceive them. In its default state a Shift will usually be near non-existent and unable to interact with reality until a being perceives and observes them. After a being has observed a Shift, the concepts that make up the Shift flow into the observer's mind until a solid identity has formed. This places the observer under the Shift's control, allowing the Shift to interact with reality, sometimes with disastrous results. A Shift's mind control ability, while extremely subtle and very powerful, has been known to be resisted by particularly powerful psychic beings, and immortals like Godminds, Transcended and the Old Brethren are regarded as immune to them. Shifts are very rarely caught, as their nature allows them to freely avoid both mundane and supernatural methods of detection.
