It got banned because the Occident are PUSSIES.

More seriously, in Europe (and later on globally), they essentially had wireless electricity transfer towers, and their entire society is built around the idea that you don't really need batteries, because the transmitter-receptor system means that anywhere in civilization, your devices will have power.

When the Indigenous Coalition of the New World launched a counteroffensive during the Futile War, they brought a Lightning Dynamicists with them. Prior to this, Lightning Dynamicists were considered scary, but required an actual thunderstorm to be manifested in order to be so. Because of Europe's wireless electricity hijinks, though...yeah, everything turned into a hella of plasma, enough so that even the Indigenous peeps were like "yeah, this is very bad news". Subsequently, the Occident and the New World brokered a truce, being the first step towards ending the Futile War.

All Technologists would be trained in standard materials that are useful for making a living, and could also have either a specific material that they are exceptionally good at altering, or a specific alteration that they are exceptionally good at imposing. Generally, you can imagine every type of material as a different puzzle; you can broadly understand how each could work, but it takes time and practice to really get to understand the alogrithms governing them.

And yeah, pitch your character idea first or toss up a character sheet draft. I generally prefer to get all the CS creation done during the interest check phase.

[@RoboCat] Sounds interesting. I'll give you a more elaborate answer later, but for now, just gotta clarify a couple of things. I can understand light, but how does sound play into this? Egoism, at any stage, basically turns the Egoist into an Endling. They are no longer able to reproduce because their genetic data has been altered, so that's essentially the end of their bloodline there. Is there a particular reason, beyond just tradition, that has them slotting a crystal in their body rather than a crystal into a tool?
