Evita was born in one of the southern nations of the Ocean Alliance. Her family background is unknown. She graduated as a Doctor of Medicine from Colom State Medical College and joined Doctors Without Borders during her PhD. After the outbreak of the North-South Conflict, Evita arrived in Kamona as a medic, and carried out fundraising to establish a temporary medical clinic that provided services for both locals and operators. She is said to have come to Kamona to find her father, a medical expert who disappeared some months ago, and she is currently commissioning operators to collect clues.
