Sandra is the leader of the Red Wolves mercenaries.
She was born into a successful family and lived free of worries until she was 17 years old, but at that point life changed. Terrorists descended on her town, killing everyone she loved.
She joined a band of mercenaries and learned to fight, selling her gun to the highest bidder. She managed to rise in the ranks and crush all that's in her way, quickly becoming a force to be reckoned with.
