The initial design was the most complicated part, really. Once an object has been embedded with the complex fractal knot pattern, made of otherwise ordinary electrum wire, Guy suffuses the wire with extra-dimensional energies. Getting the right energies, and getting them to stick, can take some doing. The wire then guides the magic, which responds readily to a simple flex of intent.
When called upon, space twists into a fractal knot that expands from the wire, distorting perceptions of the object and surrounding space. As if it had always been there, one object is replaced by another, and space returns to its natural state.
No complicated on-the-fly calculations necessary.

Description:
The Shadow Briefcase is an unassuming, sleek briefcase on the outside, but inside, it houses an array of advanced technological tools designed for the secure handling and, if necessary, the selective and legal disposal of sensitive evidence.

Technological Features:

• Quantum Encryption Module: Documents or digital evidence stored within the briefcase are encrypted using quantum cryptography, making them virtually unhackable. Only the lawyer and authorized personnel can decrypt and access the information, ensuring unmatched confidentiality.
• Biometric and Retinal Lock System: The briefcase is secured with a dual-lock system that requires both a biometric scan (fingerprint or DNA) and a retinal scan, ensuring that only the designated legal operative can access its contents.
• Selective Evidence Disintegrator: A built-in mechanism for the destruction of physical documents and digital media, which operates under strict legal protocols. It can disintegrate materials into atomic dust using pointed directional lasers.

Tiny electronic robots emerge from the ring and burrow under the users skin. They crawl along under the dermis creating quickly moving bulges that travel into the users fingers, down their hand, past their wrist, and into the forearm before ballooning outward and spreading all over the body. The feels like their nerves are on fire as the tiny insects crawl along the internals of the body before finally arriving at the nerve receptors for the eyes and nose respectively. Once at the eye the user would see their tiny legs begin to snake into the their vision from the periphery. The nanite needs the eye to be looking forward so as the cornea moves to the side to see the legs they retract while legs on the opposite side continue to snake forward. Once the eye is stationary enough the bug legs lock it into place and another nanite crawls from the back of the eye and enlarges over the cornea. Once in place it's tiny legs inject past the cornea and into the optic nerve behind it. Afterwards the user sees a thin HUD outline of what the other nanites have already found relayed back to the user. As for the nose once the nanites are in place at the nerve ending the user would have a sudden drop where they couldn't smell anything for a few seconds followed by the smell of metal and burning plastic for a bit, then the new senses would be online. The nasal cavities become filled with tiny nanites buzzing and humming from inside.

Tiny nanomachines begin to pour out of the ring and skitter around the user in an outwardly growing sphere. They burrow into floors, walls, roofs and doors and continue to move unnoticed with the user for the duration of the ability before dissolving. While active the bots scout slightly ahead and ping back information to the ring that they emerged from, mainly focusing on electronic items but also recording interesting smells and cataloguing them for investigation.
