Déjà Fu

You are just moving at what to you is normal speed, but in smaller and smaller fractions of time than the time which is being experienced by everyone around you. (Anyone who cannot slice time might, if they are really fast, be able to run a hundred metres in ten seconds. However, if I can walk a hundred metres in a tenth of a second without unduly exerting myself, by the time you have run that hundred metres, I have covered a kilometre.) When you are slicing time, everything around you appears to freeze, and to move to the blue end of the red shift (ask an astrophysicist). From the point of view of somebody outside the time slice, they might just glimpse you as a very fast red-coloured blur (and then put it down to a floater in the eye, or an after-image, or something).

The practical upshot of all this mucking around with time stuff is that you can get from the Pole to the sea on foot in a matter of days, as measured by consensus time outside your localised slice. And without exerting yourself. Sounds simple, but the Time Ninjas spend a lifetime, or (Ban permitting) several lifetimes learning how to do it. Unless they're called Inga, that is, who was born with the knack.

Ordinary mortals are also capable of slicing time, if under great stress and if they've already been exposed to the fact that Time is more flexible than we think.
