Her development was early since the 2000's and was hidden away due to redevelopment and sudden lack of interest. But soon the character became resurrected for the new place of the series Protectorate. Taking on the role of the investigator who is obsessively looking into the deepest secrets and developing a real knack for getting in and out of trouble when it comes around.
Syrienne at a young age was a unusual girl not because of her talent but because of her physical characteristics. Her father's side was a mix of Foxes and Timberwolves while her mother's side was cougar. It was a miracle the she survived birth and grew up healthy. Became a star athlete in her high school track and field team until and she does her best to hide her unusually large and powerful calf muscles.
Syrienne's coat was normal just like the rest of the others until she got older and started to develop patches of bluish fur over where her normal red-beige hue is until she became more like the "sore-thumb" of the group being the only one with a genetic defect that cause this particular change. But that didn't stop her for what happened next after single-handedly stopped a criminal with monstrous abilities.
When Syrienne caught the criminal, a nearby Protectorate agent thanked her for the assistance and suddenly offered her the chance to join the Realms Protectorate because normally she have just taken down someone that would have killed her if he had the chance. It took a while but soon enough she joined the Realms Protectorate as an apprentice agent over the years and it was long until she became a full agent to take on more dangerous missions.
