Appearance: The book is made up of three scrolls. The scrolls are all of uniform length (18 inches approximately) and are 14, 13, and 18 feet long, respectively. They are made of a type of papyrus that is tough, but extremely thin. The scrolls are wrapped around a single ebony rod (extreme age and an obscure chemical process peculiar to Atlatean bookbinders have left the rod as hard and smooth as marble). 

The scrolls are written in a neat bureaucratic hand which is friendly to the eye. The end of the scroll that is not attached to the scroll has a raw silk cord with a tassel at the end.

While the scroll is being read this rod is held in the right hand while the left holds the undyed tassel that is attached to the left edge of the scroll.

History: This book was copied as a text book for youngsters in the years before the fall of Atlantis. Unfortunately, bar going to Carcosa, time travel is the only method of acquiring a copy. The last copy was destroyed by looters when Napolean's Army fled Spain in 1813. I could go into more detail, but the Book of Drad is so pedestrian that it hardly warrants the time required for research.

Length of Study required: Appoximately four days and one successful Read Atlantean check.
Cthulhu Mythos gained: 2%
Sanity Loss: 1/1d4.
Spells Contained within: Consume Likeness.

However there enough information within the book to allow a reader to  identify (but not cast) and know the effect of the following spells: Voorish Sign, Grasp of Calumbra, Brew Space Mead, Create Powder of Ibn-Ghazi. Recognising each of these spells requires an idea-roll once the book is read.

Knowledge Contained within: A basic outline through description and various inferences, of ordinary Atlantean life during the reign of King Kull (a reader whoassiduously studies this part of the manuscript for approximately a week and a half will gain, Lore:Atlantis at his EDU+INT), and an incomplete description of the Serpent People and their powers of shapechanging and sorcery (a reader who studies this section of thebook for a week and a half will gain Lore:Serpent People at the average of his EDU and INT).
               
That's about it, really. The book of Drad isn't a very interesting book, it merely contains some unusual information. It was written by a bureaucrat and is fairly readable. Should you get your hot little hands on a copy, I would suggest skimming it and concentrating on the sections on Atlantis and the Serpent People. The book might be used as a method of introducing a new scholar to the Mythos as it is fairly readable and (as Mythos Tomes go) pretty tame.
