The first witness to testify in the case against Nxivm leader Keith Raniere took the stand on Wednesday for the second day.
Sylvie, 32, said she had been a member of the group for 13 years, and was in the process of planning her sex slave branding ceremony when the group finally fell apart last year.
Just as harrowing was her description of the extreme lengths she went to starving herself and exercising at the direction of Raniere and Clare Bronfman.
She said that at one point she weighed just 88lbs, and was training six hours a day to be a competitive runner.
That training ultimately resulted in her developing an abscess that became a fistula and required surgery.

Heiress: She joined Nxivm at 18 after learning of the cult through Clare Bronfman (above), whose horses she tended to
A medical professional told her to stop working out, but she said that Bronfman told her it was fine to exercise at the same rate so long as she was not in any pain.
Sylvie later broke down in tears while speaking about an unwanted sexual encounter with Raniere, who she had been ordered to seduce.
‘I felt shame,’ said Sylvie of the day she went to Raniere’s home so he could perform oral sex on her.
When it was over, he took a photo of her genitalia.
Raniere has pleaded not guilty to charges including sex trafficking and child pornography, and his lawyer has argued that he never forced any women to act against their will.
He faces life in prison if convicted.
Sylvie told jurors how her involvement in Nxivm eventually led her to become a slave in DOS, where she submitted herself entirely to a ‘master’ named Monica.

She recited a lifetime vow to obey her female master at a commitment ceremony and wore a necklace called a ‘dog collar.’
As was expected of slaves, Sylvie recruited other women to join DOS.
She now lives in England with her husband, also a former Nxivm member, and testified under an immunity agreement with prosecutors.
‘We were taught that women were self-absorbed, narcissistic,’ she said.
‘I feel like in some ways that was the worst part of it for me.’
