Nanomancer

Nanomancer
In many corners of the globe are Mancy Shops, where specially trained individuals called Nanomancers utilize their knowledge of ancient OE Tech to calibrate, repair, and build devices capable of creating Magic. Which Nanomancers are often eccentric, odd, and a bit off-setting, their work is invaluable as one of the last links to the old world decades before the Great War. It is not known how Nanomancers gain their knowledge, whether by seclusion in clandestine camps hidden away from the world, self-study, or otherwise. But their skills are a closely guarded secret shared only with the ones they hand-select as protege. No one else.
