Essime was born into privilege and wealth. Her father is Anton Larant, leader of the highly controversial StandardBearer Movement, a human supremacist politcal party that some would say is closer to a cult. It has over the past few decades spread throughout certain sectors of the Federation and not without incidents such as a coup attempt on the planet Haldorin, that killed Flavian Larant, Essime's oldest brother and selfdeclared coup leader. Still the Federation is a big tent and the StandardBearers are not illegal though are viewed with suspicion by many.
Essime is very intelligent and has always been an excellent student. She never just coasted on her IQ but has coupled that with applied effort. Nothing but the best has always been the expectations from her hard-driving ambitious father.
Once the girl began to focus more on a specific field in her educational journey, she found it in computers, especially programming for software. So it was an easy choice for her to major in computer technology once in Star Fleet academy.
While Essime is highly competent in her field, she does have her weaknesses such as social skills. Essime comes off across as arrogant and quick to be critical of others or situations. And certainly a part of her is very defensive, given her family background. Her father has not helped, constantly warning her that Star Fleet is no doubt trying to sabotage her behind the scenes, not wanting someone from the StandardBearers to actually attain Star Fleet officer's rank.
Essime is driven to succeed, please her father, and show the Federation she is indeed Star Fleet material.
