Well maybe not all, but some.
There are NO electrons, no electricity, no lightning, no stupid shocks when you touch metal after sitting in your shag carpet car.
Instead living creatures have cells that break down atomic level goodness into energy. Think of something like a naturally occuring nuclear reactor. 99% of the time this works in a passive state, providing the energy your body needs to power your muscles. I'm playing fuzzy science for the direct reason that my last biology class was highschool, and my chem class was poorly attended in college. Also this is fiction and NONE of this would show up in a book. The book version is: We've got energy woo!
Living creatures can -naturally- burn this energy, much like you would use addrenaline. The extra burning speeds up everything, makes you stronger and seriously wipes your caloric reserves. You have this in addition to addrenaline. When burning energy your eyes glow slightly and you feel warmer. Most creatures have a naturally occuring throttle that helps controll how much energy they create so they don't overheat or burn too much. You can controll this much like you control your breathing, with training. Most of the time you don't :P.
Certain crystaline structures at a very basic level can tap into the energy that is being released into a living creatures body by the cells. Specially crafted inks can take these molecular structures and make glyphs that do more. Glyph = circut board ... if you want an analogy for how this works. Different crystals different effects.
Scribes = engineers. Tattoos = cybernetic enhancements.
I'm describing these in OOC terms. Plants also generate energy but the energy created is a flat constant based on the plant and is more diffused.
So... no flying, no telepaths naturally. With glyphtech.... maybe. But the wer* would look like a tattooed version of Iron Man.
Phones: The device was named The Eminusdictum. or Distant Talker. Slang shortened this to ED and MED(mobile ED). Med's work by sending waves of stuff to recievers in crystal towers that then send waves of stuff to the far Med. Ed's work by sending encoded bursts of energy along glyph relays to other Ed's.
Gah lots of cases just came in. Thats it for now.
