Used to be known as Ming I, but after being cursed to be Nameless and eventually being uncursed, she decided to change her life, and has opened an Alchemy shop in the Copper District of the Dragon's Throne. She still does occasional work for her old bosses (The Alchemist and Precious Jade), but it is (or she wants it to be) more transactional. Her wares are spirit/demon oriented rather than being sorcery-oriented. (e.g. if you had a little bit of Air Spirit power, she could build you a water-breathing ring based on that.)
An Old Buddy Told Li Merit (a while ago, prior to any radiation accidents)
Ming I is twenty-four, the daughter of the Ming Hidden City family, her parents both powerful in the civil service. When she was in her mid-teens, she started being able to see and speak to spirits and demons; this was briefly thought by her parents to be an overactive imagination or madness. However, it got sorted out, and then she joined the Temple of Open Reflection, a Spiral Path temple. She spent three years there as a novice, but left instead of joining the order, to her parents' displeasure. She left the Hidden City - it's not clear where she was during that time, but was likely travelling rather than in a single place - and returned four years later, highly polished in the arts of feminine wiles. She spent some family favors that she talked out of her father to get audiences with some of the greater arcane masters in the Hidden City, including the Imperial Alchemist, and was hired by him later that year. She has not been given an apprentice's contract, but is instead a paid employee; he seems to value her spirit abilities more than her potential talent for sorcery, though he is teaching her mastery of multiple elements.
