At 16 years old Achimenes was travelling with her father on a freighter that was attacked by pirates. The freighter sustained heavy casualties, her father being fatally wounded and she sustaining such heavy injuries she had to have parts of her replaced with cybernetics, and even now there is scarring. There was, however, a silver lining: she took this as an opportunity to transition, as Achimenes was assigned male at birth.
Not long after, Achimenes was found to be force sensitive, and when she was sent off for training, she took it as an opportunity to leave her old identity behind her and forge a new one.
