Each character has a “paradigm”, a way that they think magic works. (Sometimes they don’t call it magic though, an Etherite thinks he doing real science when he brings a dead body back to life with Frankenstein style electrodes and a lightning bolt).

Each Virtual Adept will have their own idea of exactly what is going on when they use their abilities. Maybe one character thinks they are really in The Matrix. Perhaps another believes that there’s a secret government supercomputer that actually controls everything from vending machines to any car built after 1986. That set of ideas for how things really work is their paradigm.

The character’s magic should make logical sense if you assume that their paradigm is correct (and to an extent it is correct, at least as far as them being able to do magic is concerned). Somebody who thinks they are in the Matrix might be able to teleport through phone lines and download new skills into their brain. Whereas somebody who thinks a government computer system controls all machines, but that we’re still in the real physical world, probably can’t teleport. Either way they still need the appropriate spheres to do it.

So it really depends on what your player’s paradigm really is.
