The Adventure Time Encyclopædia: Inhabitants, Lore, Spells, and Ancient Crypt Warnings of the Land of Ooo Circa 19.56 B.G.E. - 501 A.G.E. is the first official guide to Adventure Time. It was written by Martin Olson. The book itself is told from the point of view of the character he voiced, Hunson Abadeer. Pendleton Ward also contributed new content. Artists including Renee French, Tony Millionaire, Celeste Moreno, Aisleen Roman, and Mahendra Sing added 150 full-color illustrations. It was designed by Sean Tejaratchi.[1] It is 160 pages long, was published by Abrams Image and Summit Media and was released on July 22nd, 2013.[2]However, the book may be non canon for example it says Marceline can levitate as a child, but she could not since she only was able to do it as a vampire shown in Adventure Time Mini-Series: "Stakes". This is likely because the book was written during Season 4 of the series, so Martin Olson made up his own information, much of which was later contradicted by canon.

Summary[]

[This summary taken from the back cover]

EVERYTHING YOU NEVER WANTED TO KNOW ABOUT ADVENTURE TIME!

Written by Lord of Evil Himself, Hunson Abadeer (a.k.a Marceline the Vampire Queen's dad) to instruct and confound the citizenry of the Nightosphere, Adventure Time Encyclopædia is perhaps the most dangerous book in history. Although seemingly a guidebook to the Land of Ooo and its post-apocalyptic inhabitants, it is in fact an amusing nightmare of literary pitfalls, bombastic brain-boggles and ancient texts designed to drive the reader mad. Complete with secret lore and wizard spells, fun places you should visit and places where you will probably die, advice on whom to marry and whom not to marry, how to make friends and how to destroy your enemies--this volume includes hand-written marginalia by Finn, Jake, and Marceline. Arguably the greatest encyclopedia ever written since the beginning of the cosmos, it is also an indispensable companion to humans and demons who know what time it is.

Only the most Diligent, Courageous, and, Stalwart Alphabet Absorbers will even continue reading in such an irritating, time-consuming manner, as reading backward, and even You want to stop but somehow find that you must go on, for fear of missing the Secret Material that surely must be included at the end, rather,at this case, the Beginning , of this Backward Forward.However, in fact, there is no Secret to Be Revealed at the end of All. This is only a Practical Device to Torture You the Reader, to make You Worthy of Further Reading. For it is Only by overcoming this Aggravation of the decidedly abrasive and off-putting literary drudgery that one can qualify to be a Reader of Hidden Secrets. And since You are about to reach the end, or rather, the Beginning, You now have proven Yourself of this Encyclopaedia of the Land of Ooo and Its Priceless Secrets Hidden inhere. The End.
