Background
Kara was raised on her homeworld of Corellia. From a young age, she spent time with her father, a local diplomat, learning about the intricacies of diplomacy and court. It wasn't exactly glamorous, but spending time with people has made her fairly confident in front of others.
As a child, she was found to be force-sensitive. Being in the Empire, her and her father tried to keep it a secret, lest she be taken captive and killed, or worse.
When she was a teenager, her father was killed in a hit-and-run. It was declared an accident, but she thought otherwise. Thinking herself at risk, and not knowing what she should do any more, she decided to leave Corellia and go in search of a purpose, and for someone to help her learn about her own unknown power.
