I believe the book of Revelations is mainly about revealing the spiritual reality of the world, not the end of the world (or at least, it's end in the sense of "where the material world ends, the spiritual world begins").
The book of Revelation, different from an icon, is a window, not only to heaven, but to *all* the spiritual reality in and around us.
In this book, prophecies are a consequence of the fact that the material world reflects the spiritual. So the Anti-Christ there is a type that has been manifest in millions of men and women. In some, it was much clearer and probably, at some point, we will have an individual who will be the perfect manifestation of that type. When and how that will happen, not even the Son knows. But, being a demonic figure, he will be about seduction, power and persecution of Christians, both through cooptation (seduction) and outright destruction (power).
