Adventure Time Encyclopaedia

 Inhabitants, Lore, Spells, and Ancient Crypt Warnings of the Land of Ooo Circa 19. 56 B. G. E. - 501 A. G. E.

Written by the Lord of Evil Himself, Hunson Abadeer (a.k.a. Marceline the Vampire Queen’s dad), to instruct and confound the domonic citizenry of the Nightosphere, THE ADVENTURE TIME ENCYCLOPAEDIA is perhaps the most dangerous book in history.

Although seemingly a guidebook to the Land of Ooo and its postapocalyptic inhabitants, it is in fact an amusing nightmare of literay pitfulls, 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 how to make friends and destroy your enimies, this volume includes handwritten marginalia by Finn, Jake and Marceline.
