    Said it before and I’ll say it again: just because you understand the magic doesn’t make it any less magical. A wizard may know the ins and outs of their spells, but they’re still spells. Our entire universal is fucking magical, we just happen to have a decent understanding of why (some) of it functions the way it does. Jiggle a quark here and another may jiggle the same way somewhere in the vicinity of Betelgeuse, that’s fucking wild and magical and incredible, and just because we have some level of understanding behind the mechanics doesn’t make it not magic. It just makes it a hard magic system.

      that’s crazy to think about. which NT is responsible for sending a signal along my vagus nerve to my brain? what NTs regulate the functions of the sympathetic nervous system? how can transport as quickly as my body reacts? I need to know more!

      how quickly do NTs even travel? it feels like electricity because it’s nearly instantaneous! how do they do that so fast???

        it feels like electricity because it’s nearly instantaneous!

        It takes hundreds of ms for a signal to go from your brain to your foot. Electricity on wires travels several times around the world in that time.

        But for most of the distance the signals do travel as electricity. (At least the ones that get to be electricity, our brain has several kinds of signals.) It’s just a particularly slow form of electricity.

        It’s a basic AC rectifier, the resistor represents an arbitrary DC load. You use similar circuits all the time, though generally with additional failsafes and some mechanism of smoothing out the rectified current.

      That’s not a resistor it’s actually a BIG LOAD. The diagram would better show it as a reactive load (usually just a rectangle) since most real loads are reactive. Get it?

              The trouble is that even the consciousness maintenance needs power. If the power is out for too long the infrastructure is too damaged. So it actually does return when you turn it off. It just has to be done quickly enough.

                That’s why electroconvulsive therapy uses pulses of about a millisecond. But, then, it’s not actually turning the power off, ECT is more of a warm reset of consciousness.

    The mages of Electrical Engineering reseach the tools and formulars to control the magic. The mages of Hardware Engineering develop under great effort the sigils and rituals of how the rocks must be processed. The Warlocks of the CPU use the near infinit possibilities of algorithms and the power of the evolved rocks to create worlds nobody could ever have imagined (in exchange for the ability to go outside).
