Mirah was born into slavery, her mother having been arrested before her birth. Mirah was put to work as a house servant as soon as she was able to walk. As she grew, her sorcerous ability sprouted. Mirah's mother, realizing this opportunity, sold Mirah to end her own enslavement.
Mirah was sent to learn how to control her abilities, and after the necessary schooling, was immediately put to work. She enjoyed a rather free life as a slave because of her magic, but when punished, it was harsh.
As she grew, so too did her strength. Her master, knowing what may happen if she grew too powerful, has decided to cut his losses with Garavel's mercenaries.
