Jester

"Jester was born into a hardworking mining family in the Twin Souls clan. She never showed much aptitude for mining; her capricious, happy-go-lucky attitude was not a fit for the dangerous, methodical lifestyle of a miner. Instead, she chose an even more dangerous route by joining the Fist of the Twin Souls - the security forces charged with protecting the clan's interests at the colony and abroad. Her acrobatics in combat, not to mention her carefree approach, left her with the nickname "Jester".

Once known for her lighthearted nature, Jester's entire world shifted when the Krall slaughtered her parents and friends."
