Though only a Magus can perform an enchantment, metal that is already enchanted can be altered(carefully) into a new form by an artificer. Many less affluent artificers work primarily with recycled parts, rather than partnering with a Magus. 
Most enchantments are destroyed at high temperatures, but the metal can be heated enough to reshape it before the enchantment breaks. They cannot be melted entirely, however. Alterations have to be made through an arduous cycle of heating, and reshaping by force. It is far too easy to tip the temperature too high and lose the magic. 

Though the Automata Corps is responsible for keeping peace and apprehending criminals, judgment is dispensed traditionally by members of the Royal Family. The seriousness of the case determines how high up the line of succession the judge comes from. Petty criminals often have harsh punishments doled out; lower members of the family have been known to sentence criminals to stripping of their Technomancy, only to turn around and sell it for recycling to line their own pockets. 

The Magi, as the richest level of Everden society, determine the height of fashion. They enjoy complex, and carefully controlled outfits. Tightly fitting waistcoats and trousers, ties tucked into their vests. Outfits never have excess fabric or freely hanging parts. Jackets are short, not extending below the waist. 

In keeping with the fashion theme of neatness and order, hair is often carefully braided, or sculpted meticulously with copious amounts of styling products. It is also very popular to keep one's head shaved. 

Most of these fashions are specific to the Inner Circle, though the highest social circles are known for selectively eschewing stylistic norms to set themselves apart. This is something a lower Magus could not do without being a subject of rude gossip. 

Palladium: stores information, encoded in the magic. Can therefore store commands and instructions, and is necessary for any automated function, as well as the transferring of a living consciousness to a machine. 
Difficulty: It ranges. A simple message stored would be 3, but creating a functioning automaton would be 10. It's easier to transfer a consciousness to an Automata body than to create and intelligence, hence the Automata corps using volunteers rather than artificial intelligence.
