"If you seek truth, enter."

"Sex, Drugs & Rockefeller"
Notorious bad boys and girls of the secret world, the Illuminati are also the most ambitious, cut-throat and furtive of the secret societies.
From the gilded halls of the ancient pharaohs to the private clubs and the decadent parties of the famously rich and egocentrically famous, from leaders of industry and Hollywood agents to presidents and popes, the Illuminati have weaved their intricate web with ruthless cunning and acute skill.
They rule their corporate pyramid with cold opportunism, and only the strongest members survive. Their secrets can make you rich and powerful beyond compare - or they may destroy your soul and sanity with it
The Illuminati seek to plunder heaven and hell by any means necessary, and god help those who stand in their way.
As a member of the Illuminati, you don't play by anybody's rules. There are no rules. There is no honour.
There is only victory.

These guys are much more about re-inventing themselves rather than being still stuck in the past. These guys are the archenemies of the Templars. They have contacts on different levels of governments, the corporations, they are the guys that, don't deal with the president, but wine and dine with the people of the west wing and the chiefs of staff, they are more subtle than the Templars. They believe in showing off money, showing off power, not revealing who they belong to. They have a very strict pyramid structure and is not about what your family is but about your accomplishments, and at any time anybody can get stabbed in the back by the next guy... These guys are pretty hardcore.
