A term used to describe transporting yourself from one place to another, it is a demonic power.
If you were to witness it, the best description I can give, is that the person sort of vibrates at a high frequency and their image pales to nothing very quickly. It is a very unreliable method of transport until a degree of power is accumulated and trained and developed. Though this can occur by accident. Lots of things can unintentionally happen when “shimmering”.
But I would like to re-highlight that this is definitely a demon only thing.
