Technomancy
Technomancy is a school of magic that was discovered during the waning years of the Steam Era. It specializes in the manipulation of electronic devices such as computers, guiding electricity to activate specific transistors into making the computer act a certain way. While it was theorized to be possible through lightning magic, it proved impractical as most mortals lacked the mental acuity to be able to perform the required spells to guide the electricity through countless transistors. During early experiments, at best, someone could use technomancy on very simple electrical circuits, but doing anything meaningful on a computer beyond shorting it out proved only useful in very niche cases.
The discovery of blue sap was what allowed for technomancy to see a surge in its use. Because blue sap puts a user into a heightend state of mind, it then becomes possible for a mortal to use their added mental computational abilities to perform the specific uses of technomancy. As such, this enabled a mortal to interface with almost any computer system using magic alone. This also allowed for further advancements in golem technology from using analog systems to digital.
