Bit of with you Hach. The Equestrians do not share there technology or mining techniques like that. The secrets of Equestrian tech aren't in open public schools like that. Also a Hach wouldn't be able to become a citizen which is required for acess to Equestrian schools. They have a closed border policy wherein only races of magical ability are allowed to become citizens or accepted races, which none of the Hach races are.
