Almost nothing is known of Lazuli’s past, even to her. The earliest documentation of Lazuli was when a young man who claimed to be her brother left her at the Eyeron Flotilla in the year 1782 GHT, making her only eight years old at the time. From the start she was ostracized by her peers and was taken into child care by the flotilla’s school counselor and biology teacher, Dr. Barret. This embittered her to the world and to people, especially boys, who loved to make fun of her for how underdeveloped she was for her age and how she had yet to start bloom despite puberty already beginning, and how often she was passed up by boys for more mature looking girls.

Lazuli is what's known in Soulek culture as the Pale Soul, a female Soulek born once every 100 years and is supposedly the reincarnation of their goddess known as The Lightess. Because of this Lazuli feels crushed by the weight of being the chosen one to people who reject her for sins she did not commit thanks to the previous Pale Soul.

Lazuli is bratty, short tempered, not a fan of boys, and extremely independent. Yet has a heart of gold beneath her prickly exterior. She can't help but help those in need and has a soft spot for those who look past her supposed divination to care for her for who she is, rather than as just a reincarnated goddess. She also is far shorter than the average Soulek for her age (being only 4'2) and very underdeveloped. This fact is a very sore spot for her.
