Apr 27, 2019 at 21:06 comment added KConrad There is already a name for Galois elements whose behavior has been very fruitful in number theory: Frobenius elements or conjugacy classes associated to prime ideals. They are not as down-to-earth as complex conjugation ("Frobenius at infinity"), but they are dense in Galois groups over $\mathbf Q$, which is very nice.
