Jocelyn was born to House Sirl amidst a strange time. Her father was still young at the time and learning how to run a House after the passing of his own father. He did not find much time to spend with young Jocelyn and nor did their mother. She had her siblings, but only some of them seemed to take an interest in what she wanted to do. For a long time she felt extraordinarily alone due to the nature of the House.

As she got older, she gained a robust distrust for those around her, and the magic passed onto her played nicely into this. She was never deceived nor tricked by anyone in the household and found herself learning a lot of what actually went on with House Sirl: the manipulation of the populace. She did not reject this idea. The idea that her House was attempting to shift the rats below into doing what they wanted seemed... Fun, if nothing else. Eventually her talents were used for this, and she grew a bit closer to her family from it.

Once she turned seventeen, she started going to parties as an informant, which is where she developed her more distasteful qualities, as put by her father. She was very good about learning things but would often not come home that night, only to be found in bed with a boy she'd met that night the next day. This never really changed. She is good at what she does but is easily distracted by the pleasures of life and would prefer to live that way then to become some grand arbiter of the people.
