Magic-Technology
It has long been believed that City Elves were formed from the concrete and neon, and the plants that grow between; creatures of man-made magic just as other Fae were created from the Earth. As such, they have always had a deep connection with human technology and culture.
For decades -- centuries even -- the City Elves lived among us, finding ways of honing their magic subtly or through scientific means. Thus, Magic-Tech was born.
It began as small enhancements to fashion accessories, or subtle upgrades to already existing technology. Post-Uprising the inventions were far more open (though still held some subtlelty and fashion picked up from all those years). Soon technology was being developed that would directly root into peoples’ skin, either as a body modification or for a specific purpose. Medical technology began to emerge, and magic-run modes of transport. It was a magic-industrial revolution of its own, and yet City Elves are still the primary users of their tech.
Astoria is the primary human-run hubris of magic-technology; having developed their own version of the Elven concept from the discovery and study of magical artifacts.
