Growing up under the yoke of Cheliax, would crush many people down, and for tieflings, it was a horrorshow with no escape options or hope. That doesn't mean everyone was going to go down that same path, and Resa Dermade was excited and kept her hope that things will get better. She remained a good person even as her life went from youth in shackles to a young woman in shackles, but the only real change was she got more quiet and solid in her belief she would one day be free and see the world.
One day things did in fact get better, and suddenly she was free from the life of being chained to people who did not care for her, but only cared what she did for them. She took the chance to move from the area where she was born, and turned her life to the church of Desna. While not always on the best behavior, she was often excited and able to give praise to the Goddess of travelers, for in her mind, the ability to move was the ability to be free. And what better way to pay for freedom than by helping out others of their problems?
