Mirra was born into House Medani from two dragonmarked parents. Her mother, Sorra, is a lesser dragonmarked heir that spends most of her time in Korth in the Twelve enclave as a House Medani diplomat. Mirra’s father, Raiden, put his greater dragonmark to use and is now one of the most well known inquisitive in Sharn. Mirra grew up in the upper towers of Sharn spending most of her time with her father as he trained her in his trade. Both her parents waited patiently for Mirra’s dragonmark to manifest but soon they realized that her mark wasn’t going to come.
During the War Mirra and her parents kept their neutral positions and managed to stay away from most of the direct battling.
About ten years ago after the hope of having a dragonmarked daughter became a distant dream Mirra’s father started to loose interest in her training. She soon started mentoring under a contact from the Phiarlan house that Medani secretly used. Corvin was the Phiarlan’s name and he started teaching Mirra his deceptive ways and she soon returned to work as an inquisitive with a different view.
Right after the end of the War Mirra started working some small scenes and jobs and one of the scenes she walked into was the start of a long killing spree. The first murder was pretty insignificant; a strangled prostitute in Firelight, the only clue was the garrote was a silver ribbon. For the next six months two more girls would end up dead and the same silver ribbon was found. Soon through other line in the Medani House Mirra started to suspect that the murderer was a high ranking noble but she could not tie him to the murders. As she showed up to another three murders Mirra was the first one on the scene and using her skill at slight of hand she lifted something from every body, a necklace or some hair.
Finally when the time was right Mirra used a large gathering and picked a broach off the nobleman. Later that night she broke into the his flat and place a polished wooden box filled with the ‘souvenirs’ deep in a chest. The next murder Mirra was the first to show up and she placed the stolen broach in the victim’s bloody hand.
The after math of several Medani agents and the Sharn watch finding the evidence in the nobleman's quarters was that talk of Sharn but even the hip couldn’t silence all the protests from the diplomat. Soon Mirra’s superiors started looking closer at her actions and some started to suspect and know she is working the menial job the enclave receives to keep her out of the way.
