This pair of companions are sisters, but they couldn't be more different.
Diablita has horns, hooves, red skin and a tail. She wears nothing but tattoos and piercings, and carries a pitchfork (staff weapon).
Angeline has flaxen hair and wears lace and satin. She also sports a golden headband that looks suspiciously like a slipped halo.
By The Elder Scrolls rules of genetics, they resemble their respective mothers, but have a common father.
It all starts after you find the pair in your basement when you purchase the Imperial City Shack.
