One of the first Auran abilities Rix (inadvertently) demonstrated in the story was the "mach sprint". It doesn't LITERALLY make you run at supersonic speeds, but you can temporarily run a whole lot faster than any normal person (and even a normal Auran) would be able to. It's one of the few times Verrocite actually charges its owner's Aura instead of the other way around, and a useful ability.
