Garnet spent most of her early days locked away within her adoptive parent’s estate due to the sickly disposition with which she had been cursed, with little else to do but study the piles of astrology scrolls and instruments littering her parents’ study due to their prestigious position as court astrologers. Garnet’s adoptive parents soon began to resent the needs of their sickly girl, a coldness soon reciprocated. The mother eventually gave birth to a son, Garnet’s “younger brother”, who thenceforth became the sole recipient of the entire household’s attention.

It was on a routine astrology consultation that Muriel, the wife of a local duke, spied out the seemingly-insignificant Garnet from the large banqueting hall, and was immediately struck by her quiet and mature disposition. She found herself rather astonished the girl had not been introduced, something about whom reminded Muriel of a child she had lost years ago. She could not help but approach Garnet and, warmly extending her hands, asked: “Would you like to come with me? I’ll take you to see more of the world than these four walls.” Garnet was no fool and knew her options at home were decidedly limited. She agreed and, oddly enough, departed with Muriel the same day on the condition she be allowed to bring her astrology implements. Muriel quickly realized Garnet had the ability to become someone truly extraordinary without her sickly physique, and thus went to great expense to commission a mechanical marvel from the hands of renowned dwarven forgemaster Harbeg Moltenfire which, with a little magical help, transformed Garnet’s body into a half-copper, half-magical contraption capable of protecting her from the dangers of the outside world.

Garnet’s adoptive parents never realized the true source of her sickness: tremendous magicks within Garnet’s body were simply too great for her human constitution to withstand, also explaining her aptitude for magical astrology. Muriel, delighted with her new “project”, drew upon her considerable resources to provide an excellent mage’s training with the benefit of Harbeg’s protective sheath. A strange symbiosis has since formed between Muriel and Garnet over the years. Garnet is happy enough to act as Muriel’s assassin on points of aristocratic business as long as she can spend the remainder of her time studying the stars.
