Artifice is a Sign type that specializes in the creation of magical items or the enchantment of normal items. This is achieved by either forcibly imbuing an item with magic or by taking a more delicate approach and "designing" the item to hold magic, such as etching Leylines into an object.
Artificers see most of their work go into the creation of Magitech items or the maintenance of them. The "old" culture or purely enchanted items is still present, though the market for such things are rapidly dwindling in polite society as the need for blade or bullet deflecting armor is needed less and less. Militaries and other security-focused sects still have an interest in such items, but Magitech threatens to replace these sorts of things as well. Outside of combat-oriented markets, only collectors and those with nostalgia for the older ways continue to seek purely magic items.
