The United Nations (UN) was an organization of states on Earth, chartered in San Francisco in 1945 as a forum to promote peace around the planet. Shortly thereafter, its world headquarters was established in New York City.
On August 29, 1994, Vasily Hunyadi, an Augment behind the Serbian government, addressed the United Nations in defiance against the economic sanctions and the NATO peacekeeping presence in his country. During his speech, members of the Army of Eternal Vigilance released sarin gas into the council chambers, killing Hunyadi as well as many ambassadors and tourists including Clare Raymond.
