In real life, cybernetics is the study of any control-feedback system. But the most obvious examples would be real prosthetics, like a hearing aid with an adjustable volume, or a prosthetic hand with touch sensors. Most people (including myself) think of grafting tech onto living organic matter when you hear the word "cybernetics".
In much Sci-Fi, it's usually laser-focused on the prosthetics, because turning yourself into a superhuman with microchips and metal looks cool. A common idea in Cyberpunk is questioning where we draw the line. Are there consequences for grafting too much tech onto yourself? When does one become less of a person, and more of a machine?
Elidel, like any cyberpunk world, has things like artifical muscle fibres and neural interfaces because they're cool and a staple of the genre — usually grafted in through invasive surgeries. It lets our characters become beyond human (or elf etc). Your character can enhance their strength, see through walls with a thought, or make a phone call to someone miles beneath the ground. Such things are so integrated into society that people don't bat an eye — like us and iPhones. But then in comes the question: what happens when you become more machine than organic?
I think there's many facets here that we can explore.
