Attorneys for the Eastern District of New York have made a surprise filing in federal court as they continued to gather evidence in their case against Nxivm.

A verified complaint was submitted on Wednesday in which the prosecution announced that they would like to seize property from the home of cult founder Keith Raniere as well as the townhouse owned by Allison Mack.

Raniere's property, which has been referred to in some court documents as 'the library,' is where he is accused of having sex with up to 20 woman who served as his slaves inside the Nxivm cult.

Those slaves would then return to Mack's home, with the founder's number two housing the woman when they were in town according to federal court filings.

Both homes are approximately 15 miles away from Nxivm's main campus and located in the town of Halfmoon, just a few blocks away from one another.

Federal prosecutors are looking to seize anything from the properties which would support the charges of sex trafficking and conspiracy to commit false labor.

Both Mack and Raniere have been indicted on two counts of trafficking and one of forced labor, with the two looking at sentences of 15 years to life.

The complaint outlines some of the reasons that prosecutors believe they might be able to seize vital evidence from the properties while revealing new details about the cult.

It starts off however with outlining the DOS faction that Raniere set-up with Mack back in 2015, a group in which he was the lone male.

'Based on information obtained during the course of this investigation, since ESP's founding, Raniere has maintained a rotating group of 15 to 20 women with whom he maintains sexual relationships,' states the complaint.

'These women are not permitted to have sexual relationships with anyone but Raniere or to discuss with others their relationships with Raniere.'

It goes on to note: 'Some of the Nxivm curriculum includes teachings about the need for men to have multiple sexual partners and the need for women to be monogamous.'

The document also details the ways in which Mack and Raniere allegedly made sure that their slaves would be loyal.

'From the time of its inception through in or about Spring 2017, DOS masters recruited slaves mostly from within Nxivm 's ranks,' reads the court filing.

'When identifying prospective slaves, masters often targeted women who were currently experiencing difficulties in their lives, including dissatisfaction with the pace of their advancement in Nxivm.

'While avoiding the words "master" and "slave" in the initial recruiting pitch, a master would tell her prospective slave that the prospective slave had an opportunity to join an organization that would change her life.

'The master then told the prospective slave that, in order to learn more, she had to provide 'collateral,' which was meant to ensure that the prospective slave would keep what she was about to learn a secret.

'Collateral consisted of material or information that the prospective slave would not want revealed because. it would be ruinous to the prospectiveslave herself and/or someone close to her.'

Among the forms of collateral that were provided by the women were 'sexually explicit photographs; videos made to look candid in which the prospective slaves told damning stories (true or untrue) about themselves, close friends and/or family members; and letters making damaging accusations (true or untrue) against friends and family members and assigning the rights to certain assets.'

Prosecutors then name a second woman they claim is a slave master, Lauren Salzman.

There is also more information given about the witnesses in the case, which further spell out some of Mack's actions.

'In or about February 2016, Mack invited Jane Doe 1 to join a "women’s mentorship group," but asked that Mack first provide collateral. At Mack’s direction, Jane Doe 1 wrote letters detailing false and highly damaging accusations against her family members. Once Jane Doe 1 had.provided this collateral, Mack told her about DOS, referring to it as "The Vow,"' states the filing.

'Jane Doe 1 agreed to become Mack’s slave, provided more collateral (eventually including her credit card numbers with letters granting Mack permission to use the numbers to make charges) and began receiving assignments.'

It added: 'Throughout her time in DOS, Jane Doe 1 was living in Brooklyn, New York. Mack ordered Jane Doe 1 to travel to Halfmoon nearly every week from Brooklyn.'

Special Agent Michael Lever states that Raniere came up with the idea for Nxivm's DOS program during the summer of 2015.

A woman by the name of CC-1, who was revealed to be Mack in subsequent filings, was his first 'slave,' and provided 'colateral' which guaranteed she would remain faithful to him by providing Raniere with damning material.

'CC-1’s email was titled "vow 3" and included an attached letter. The letter pledged CC-1’s "full and complete life" to 14 RANIERE,' reads the complaint.

'In the letter, CC-1 used the terms "slave" and "master" to refer to herself and RANIERE. Moreover, the letter identified "collateral" to "cement" the vow made by CC-1.

'This collateral was described as: (1) a letter regarding CC-1 's mother and father that would "destroy their character"; (2) a contract that transferred custody of any children birthed by CC-1 to RANIERE if CC-1 broke her commitment to RANIERE; (3) a contract that transferred ownership of CC-1 's home if the commitment to RANIERE was broken; and (4) a letter addressed to social services alleging abuse to CC-1 's nephews.'

It is not clear if any of the claims made in those letters were true.

Soon, CC-1 was recruiting slaves of her own and filling out the pyramid that Raniere had hoped to create, selecting Jane Doe 1 as one of these women.

Jane Doe 1 stated that her first meeting with Raniere ended with the leader questioning her devotion, but soon things took a bizarre turn.

'The next night CC-1 again received a text message from RANIERE, woke Jane Doe 1 in the middle of the night and assigned her to meet RANIERE and tell him she would do anything he asked her to do. Jane Doe 1 did as she was assigned, and RANIERE led her to a house across the street,' reads the complaint.

'RANIERE directed her to remove all her clothes and made comments about her naked body. RANIERE then blindfolded Jane Doe 1, led her into a car and drove her around in a manner that made Jane Doe 1 believe RANIERE was trying to prevent her from knowing where they were going. '

RANIERE led, Jane Doe 1, still blindfolded, through some trees, into what she believed was a shack, and tied her to a table.

'Another person in the room, who Jane Doe 1 did not previously know was present, began performing oral sex on Jane Doe 1 as RANIERE circled the table making comments.

'Jane Doe 1 did not want to participate in this sexual activity, but believed it was 17 part of her commitment to DOS and that if she broke her commitment to DOS her collateral could be released.'

Jane Doe 1 said that she then began to frequently have sex with Raniere while also frequently posing nude for CC-1, who on one occasion sent 'close-up pictures of [her slaves'] vaginas' to Raniere.

This was not the only task Jane Doe 1 had to undertake, as she was also responsible for reading, reviewing and editing Raniere's writings and texts.

Allegations of Raniere's alarming and illegal sexual predilections are also outlined in a letter sent by US Attorney Richard P Donoghue to Judge Steven M Gold back in March.

'According to confidential sources, the defendant had repeated sexual encounters with multiple teenage girls in the mid-to-late 1980s and early 1990s,' reads the letter.

'In one instance, the defendant met a fifteen-year-old girl while he was in his 20s and had repeated sexual contact with her. In another instance, the defendant met a twelve-year-old girl whose mother worked for the defendant and began tutoring her.'

The letter goes on to say: 'Shortly thereafter, the defendant began having regular sexual intercourse with her, including at his home where he lived with multiple adult sexual partners.'

Raniere is also said to have voiced his belief that the age of consent should be lowered to when a parent believes their child is capable to sexual activity.

Mack was arrested and arraigned on federal charges of sex trafficking and conspiracy to commit forced labor last month.

Those are the same charges thatRaniere, 53, is being charged with, and both are facing a possible sentence of life behind bars.

Raniere could be spared from serving any time though, with a former publicist for Nxivm telling DailyMail.com that Oxenberg has said she is willing to take the fall for Raniere if it will keep him out of prison.

Frank Parlato, who has been covering Nxivm extensively on Art Voice, said that the female members of the cult have devised a plan they hope will save Raniere.

First, all female members are prepared to deny that they were ever forced or coerced into performing sex acts in an attempt to discredit the allegations made by the two former members whose grand jury testimony resulted in the indictments of Mack and Raniere.

If that does not work, member India Oxenberg, Mack and Mack's wife Nicki Clyne are prepared to testify that they alone were responsible for coercing members into having sex claims Parlato.

'Mack, Oxenberg and Clyne have made a pact to go to prison, saying privately they are ready to walk into prison tomorrow if Raniere could be free today,' reports Parlato.

Parlato tells DailyMail.com that Mack's arrest had been in the works ever since Raniere's extradition from Mexico to the United States back in March.

He posted video of Raniere's arrest at the time, which showed Mack in a state of disbelief as officials dragged away the self-proclaimed Svengali.

The grand jury indictment states that Mack did 'benefit ... financially and by receiving a thing of value, from participation in a venture ... knowing that means of force, threats of force, fraud and coercion, and a combination of such means, would be used to cause such persons to engage in one or more commercial sex acts.'

The first of the women to testify in front of the grand jury, Jane Doe 1, also said that Mack 'did knowingly and intentionally conspire to provide and obtain the labor and services of a person .... by means of serious harm and threats.'

Mack has yet to comment but has reportedly retained a lawyer.

'As alleged in the indictment, Allison Mack recruited women to join what was purported to be a female mentorship group that was, in fact, created and led by Keith Raniere,' United States Attorney Richard Donoghue said in a statement on Friday.

'The victims were then exploited, both sexually and for their labor, to the defendants’ benefit. This Office and our law enforcement partners are committed to prosecuting predators who victimize others through sex trafficking and forced labor.'

Mack had been serving as leader of the cult for the past three weeks DailyMail.com previously revealed, a role she assumed after Raniere was arrested by authorities in Mexico last month.

Both her initials and those of Raniere's were branded on the pelvic area of women who joined the organization.
