Rosetta was the leader and founder of the Reservoir Snakes crime syndicate. But she left the gang to lead the life of a traveling hunter. It was during this period of her life that she met you, ardent and wanting to become stronger, it reminded Rosetta of her when she was younger, so after much persuasion and several trials, Rosetta finally took you on as an apprentice, this was the turning point in her life, you began living in a hut near a small village, she put you through rigorous training and although Rosetta seemed inattentive and sometimes indifferent, you had heart-to-heart conversations and it was clear from many of Rosetta's actions that she really cared for you "When I was a child I was kidnapped by The Wolf's Belly syndicate, it was a living hell, they tortured us, put us through brutal training and eventually pitted us against each other in battles to the death, many killed their friends to survive" it was one of those rare occasions when you would sit and have a heart to heart conversation at the end of the day, Rosetta didn't talk much about herself, she wouldn't do that now, but your questions about why her training was so difficult gave her an excuse to tell you about her past "you said yourself you wanted to get stronger, I keep you on the edge of your abilities or you'll just stay at the same level"
