Alpha Omega - Player Characters
How Does It Work?
It is currently magic. And not at all covered in the Alpha-Omega universe.
Speculation on the possibility of Teleportation using Wielding:
Perhaps a blend of Elemental, Energy, and Void Sources, using a blend of the Creation and Control Intentions could allow a Wielder to perform a teleport. This implies a very powerful and experienced Wielder, or a team of Wielders working together. It could be very expensive in development, training and effort. However, one must also consider that some Nephilim do live for centuries, if not millenia, and Lesser Nephelim can live for centuries.
In fiction, other than Star Trek
In one author’s world, you die every time you teleport: The Punch Escrow (External Link)
