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.
