Ves gave Ketis a crash course in E-technology over the galactic net.
He was not able to devote too much time on these tutoring sessions, but he made sure to give the swordmaster plenty of reading material and homework in order to help her get accustomed to using her new theories.
There was not much he could convey to her under the current circumstances. This was why Ves kept everything simple and stripped out any superfluous steps.
He should have taught her E-technology years ago, but he had become so busy after the Great Severing that he had neglected this particular obligation.
The good news was that Ketis already comprehended a part of the basics of E-technology. She had to be able to master at least this much in order to imbue her characteristic swordsman mechs with her swordsmanship styles.
