Born in Wrocław, Zofia Bosak is the oldest daughter of Jan Bosak, former commander of the Polish Special Forces unit GROM. While attending her father’s military high school, she was pressured to perform on every level—a burden her younger sister was not able to cope with.

During a school trip to the Masurian Lake District, Zofia was prey to a disturbing prank that almost cost her life. While she played in the lake, three boys from her class took turns trying to drown her, just for ‘fun.’ This violent experience marked her with a deep mistrust of others. The following week, she had to sit beside her assailants in class. To deal with her growing anxiety, she decided to push her training further, and ensured she could rely on her skills for protection. Her father agreed to show her ruthless techniques, given she would never question his methods.

When Zofia hit legal age, she enlisted in the army. Among Zofia’s most notable exploits is a rescue Operation in Guatemala, codenamed Red Agatha. A disastrous tropical storm formed a sinkhole in the middle of the city, swallowing an entire neighborhood. Zofia was deployed to protect a team of scientists examining the perimeter. During a sudden landfall, she saved a child from disappearing into the abyss. To reward her ability to withstand hardships, Zofia received a medal and was promoted to Second Lieutenant.

Throughout her experiences, Zofia forged a second family overseas. To have more impact on the field, she learned to trust her squad mates with her life, re-considering the cruel lesson from the incident at Lakeland. Far away from her father’s brutal training, Zofia let down her walls, developing close ties for the first time. She met her now-husband in a rogue operation in Mali, where they both mistook each other for hostiles.

Challenged by her squad mates on the field, she discovered the true kind of specialist she wanted to become. At the peak of her career, she flew back to Poland for her wedding ceremony. The celebration was kept short, but Zofia quickly returned to Wroclaw for her maternity leave. Her arrival in Poland was soon followed by her father’s sudden passing.

The birth of her daughter had a profound effect on Zofia, igniting her need to cocoon with her family—but Ela ignored her sister’s attempts to reconcile.

Zofia returned to the GROM soon after hearing Ela would pass the selection. Except for her attempts to reconnect with her sister, Zofia kept her distance with everyone else. Her squadron noticed this change, and wondered if her recent obsession with her father’s pocket watch was a remnant of grief, or something more.

When Ela accepted the prestigious offer to join Team Rainbow, Zofia saw no reason to stay behind. Everything about the GROM now seemed to remind her of her father.

Three months later, Zofia was an official member of Team Rainbow.

Psychological report

-Underwent thorough examination, but remains inconclusive. Perhaps too experienced at falsifying test results.

-Significant divide between the two sisters.

-Their father had a key role in it. His obvious favoritism towards Zofia is well-known.

-When asked about their relationship growing up, Zofia kept her answers curt and non-committal.

-And yet, very protective of Ela.

-Refuses to discuss her father’s suicide.
