A former NXIVM cult member is speaking candidly about her ordeal. Sarah Edmondson, 42, spent 12 years in the cult led by the charismatic Keith Raniere. She said she was selected to join a secret sisterhood within NXIVM and as part of the initiation she had Raniere's initials, "KR," branded into her skin. "It was horrific," she told Inside Edition. "The whole point was to experience pain and to overcome the pain, to be really strong, so they cut our flesh open without anesthetic."
