variety of artists in the numerous volumes of this sub-series. Antipodes Two additional series (Donjon Antipodes − and Donjon Antipodes +) explore the distant past and the far future of the other series. Bonus A last sub-series called Donjon Bonus hosts works outside the comics, like the tabletop role-playing game Clefs en Mains Bibliography Since the series start, it has grown into quite a large collection of volumes. The place of each book in an orderly timeline is worked out using “levels”. The volume number of books in the main series (Early Years, Zenith, Twilight, Antipodes) is also their level. The Monstres and Parade level numbers are written down in the original books on the first page below the page number. The following table shows all the French volumes by Delcourt and information about English-language releases by NBM Publishing. The table can be sorted by series, or by chronological order using “levels”. Unless otherwise noted, all the books are written by Lewis Trondheim and Joann Sfar, with various artists. Main characters Herbert the Duck is the "hero" of the story, and appears in at least Donjon Zenith and Crepuscule series. As his name suggests, he is a duck, although he has a humanoid body, and is covered in feathers. He is the possessor of the Sword of Destiny (a parody of other mystical weapons in adventure books). This sword is unique in that it can talk, and that has many mystical powers, such as being able to glow in the dark, being able to summon former bearers when someone other than its legitimate user tries to hold it, and not allowing the use of any other weapon by its owner. Also, one side of its blade has the enigmatic property of being able to cut -and even behead- living beings without killing them. Marvin the Dragon serves as the reluctant instructor and protector of Herbert the Duck. Marvin is a fierce warrior who loves a good fight, but at the same time he is bound by the principles of his religion. He is a strict vegetarian, refuses to eat "human" or animal flesh and will not attack anyone who has insulted him. Like other dragons, he can breathe fire, but will do so only when strictly necessary. Initially caused by indigestion due to eating little blue mushrooms, Marvin is capable of producing a "Tong Deum", a large blast of fire-breath.
