Soul O'Brien
Soul O'Brien was a main character in the Netflix Original, The Bastard Son & The Devil Himself. Soul was a sitting member of the Fairborn Council, held in high regard by his peers and Fairborn Witches alike. He was also the father of Annalise O'Brien.
Following the news that Nathan Byrn could be a Blood Witch, Soul became obsessed with ensuring the events of the Wolfhagen Massacre did not reoccur, eventually leading to attempts to steal Nathan's abilities and kill Marcus Edge. This eventually led to his downfall — and arguably the downfall of the Fairborn Council — at the hands of his own daughter.
