Nakalaxi Lorgrek was a successful slave broker. She was born on the batarian homeworld, Khar'shan.
Most non-batarians found her first name difficult to pronounce. In casual social settings she usually introduced herself as Kalla.
Nakalaxi was raised by both her parents, and had eight brothers. Out of all her family members she was closest to her maternal grandfather, who helped her start her business.
Standard testing performed during infancy showed Nakalaxi to be a biotic. While she wasn't a very strong biotic, she received excellent training and knew how to make the most of her limited abilities when necessary.
Nakalaxi was born near the top of the batarian caste system, but between growing up as a biotic in the Hegemony, and living her adult life as a batarian on a planet dominated by asari, she had very few friends. She spent the bulk of her free time reading.
