Mikaela was born on Mindoir. She had three brothers and one sister. Her parents worked on the mining plant. Her uncle was the captain of the space cruiser and he rarely saw his favorite niece. Mikaela was the oldest child in the family so she had to start work at the young age to help her parents.
The tragedy occurred in her birthday. That day started as usual and there were no signs of danger. In the evening fourteen-year Mikaela took her brother from the kindergarten and they were heading home, when it happened ... The Batarian ships came out of nowhere and opened fire on the colony. A few minutes later the whole city was in flames.
Mikaela and her brother were able to reach the home where they found their mother and their two brothers and their sister. Her mother was badly injured and her father was still at the plant where he worked. Mikaela couldn’t let the Batarians to get to her father, so she decided to go to look for him.
She ordered the others to be with their mother, while she will look for their father. Mikaela was sure she would be able to save him, but she was wrong. When she got to the plant, then saw the explosion. The Batarian ship dropped a bomb on the city's main factory…
She returned home and saw like one of the Batarians had killed her mother. His face ... This face she remembered for all her life. Then Mikaela was running away from pursuing her Batarians. The bullet hit her in the shoulder. Mikaela fell into a ditch and lost consciousness.
Three days later Mikaela woke up in the medical bay on her uncle's spaceship. She was the only survivor from her family. She promised herself to revenge for her family.
“They gone.” She said quietly.
“It’s okay, Mika.” her uncle said. “You can cry.”
“Never.” She glared at her uncle. “I will never let myself to cry. Never ever again.”
At the age of eighteen Mikaela entered the Military Academy. She hoped to meet the Batarian who killed her mother. The Leader of those slavers. She trained to improve their biotic powers she had since she was a child. And seven years later she met him on Torfan. Mikaela took revenge, but she lost most of their squad.
