An 80-year campaign for Pendragon, though this book only covers the first half of it in any depth. You'll find an overview of the Anarchy period (495-509), then year-by-year descriptions from 510-531. The chronology after 531 is only covered briefly, with 8 pages for the last 40 years.

In addition there's a bit of info on London and Camelot, plus stats for many of the main characters.
