[@shylarah] As far as Rodion and his workshop goes-- each inquisitor is highly individualistic in terms of their ether ability. It's not like there's a 'metalworking class' in the seminary. In fact, I think Rodion is one of the few inquisitors who can do what he does. He showed talent with machines so a curriculum was created specifically for him, just as one was created for Tatiana and her summoning, Astraea and her healing abilities, Ziotea and her ether manipulation, ect.
