|Deus Ex mapping|
In Deus Ex, Silhouette is the resistance movement against the French government, led by Chad Dumier (who is known to the public as "The Minister of True Lies"). They have discovered that the United Nations and the French government are deliberately restricting poor people from accessing Ambrosia (the vaccine for the Gray Death disease), and are under the control of a secret organization called Majestic 12 that wants absolute control over everything in the world. They are allied with the NSF (the resistance movement against the United States government), the Luminous Path Triad, and X-51 (a group of former Area 51 scientists). They focus their efforts on subversion of media outlets to attract citizens to their cause. Their motto is "Tandis qu'ils dorment, nous gagnerons" (While they sleep, we will win). The philosophy and approach of Silhouette are similar to the real-life French Situationists. By the game year (2052), Silhouette suffered a leak that led to the exposure of one source of their funding, the wealthy French heiress and banker Beth DuClare. After a brief but torrid scandal, she was assassinated by Majestic 12.
Also during that year, an attack on the Statue of Liberty was the most-cited reason for the establishment of a standing UNATCO force on American soil. Many throughout the world suspected Silhouette, which had several months before released statements on world cultural monuments, among them a claim that the Statue ought not have been given to America. However, it is discovered that UNATCO had perpetrated the bombings to reduce support for Silhouette and its allies.
Through their leader's close relationship with Nicolette DuClare, Silhouette benefit from the financial, social, and intelligence support of the French faction of the Illuminati. Dumier claims that he doubts the Illuminati would continue to assist Silhouette were MJ-12 not a threat, but the younger DuClare sympathizes more with Silhouette. The Illuminati find Silhouette to be useful allies in their struggle with MJ-12.
