Because as it appears in The Da Vinci Code and Angels and Demons, Mr. Brown is the author.
Let me make this easier. Dan Brown is a writer of fiction, made up stories, books about events that are not entirely real. The reason that he knows "everything about Opus Dei, the Illuminati, and the Freemasons" as they appear in his novels is because he made it up. This is what writers of fiction do, some better, some not as well.
Look at it this way, the reason that John Ronald Reuel Tolkien knows everything about Hobbits, elves, dwarves, orcs, goblins, trolls, the dragon Smaug, Ents, and all the other inhabitants of Middle Earth is because he created them for his stories: The Hobbit, The Fellowship of the Ring, The Two Towers, and The Return of the King, as well as his other works. The same is true for Dan Brown.
Innumerable books have been written by and about Freemasons. Which two are of interest to you?
The Illuminati don't exist. They are made up for books so no one is part of them.
There is no group called the Illuminati. It is made up for fiction and a books.
There are no books about Chris Brown.
Ratio of green books to brown books = 2 : 3 Green books = 18 : ? The common factor = 18/2 = 9 Number of brown books = 3×9 = 27 Brown books = 27 Green books = 18 Difference = 27 - 18 = 9 books
Various places will have "information" on the Illuminati. On line would be your most reliable source; places such as wikipedia, or sites that document taboo or bizarre conspiracy theories and historical records.
Lavender Brown's hair colour was not mentioned in the books.
As the Illuminati doesn't exist, it should not be difficult to "get out.' Simply stop believing. It's a fiction boogeyman created to sell books and merchandise.
Illuminati is the Latin form of "Enlightened".The movement was founded in May 1, 1776 by Johann Adam Weishaupt, of Ingolstadt, Bavaria. Alternative names for the Illuminati are known as Perfectibilists, The Order of the Illuminati, or Illuminatus. The movement is commonly referred to an offshoot of the Enlightenment-era and is said to be modeled from the Freemasons. They were allowed to operate freely only until 1785, when a keen proponent of "Enlightened Absolutism", the Duke of Bavaria, Charles Theodore, banned all secret societies from operating. The order itself was said to have had over 2000 members in ten years, many of them prominent politicians and leaders, and most of them spanning over European countries.The Illuminati are often associated with Freemasonry. While there are some similarities there is one striking difference between them. The Illuminati were not a democratic, egalitarian movement. The Freemasons were a proto-democratic, egalitarian movement and have not changed much today. They both excluded woman from joining, yet there are female chapters of the Freemasons that exist today, and they both have non-dogmatic belief systems, both favor Deism and are not associated with Satanic or Anti-christian beliefs as commonly argued. George Washington himself was said to of been a Freemason.The Illuminati are commonly associated with Conspiracy Theories from those who support and disapprove of the organization. Those who are in favor of the Illuminati say that they are a group of free thinkers who want the best interest of the people they secretly hide from. They want to bridge the differences that come from politics, religion, and social order. Those who are not in favor, suggest that they are the group behind the New World Order, that will cause corruption and ultimately the fall of government into a Utopian society where all countries are unified into one government.
No, Alex Hirsch is not Illuminati. The modern Illuminati is a conspiracy theory that was surfaced by novels like Angels and Demons. If there is anyone at all calling themselves Illuminati, they are a couple of people getting together, not an international ring of puppet masters, like made out in the fictional books.
