Lara's mother was Part of the Sentinals,  Skyhawk was her mother, a woman with the ability to fly and always hit her target no matter what weapon she used. Lara can only guess she got her ability to fly from her mother. Her father she does not know him but is an agent of Decimator. No doubt having worked up the ranks since that time long ago. She thinks part of her power may have come from him, hence the reason she tried to find him when she was younger. He fell in love with her mother she was the outcome. Her mother died in a fire she was told it was an accident, and doesn't remember anything from that time. But there has always been suspicion and doubt in her mind about what happened.( can give gm's more details but don't want to put spoilers here. :p ) From there she was taken in by the sentinels mainly by Jack a man that was incredibly close to her mother her best friend one would say.
