Riding his tireless pterodelph, Arzak tirelessly crisscrosses the mineral expanses, flies over the overheated sands, explores gorges and ravines. Nothing escapes his alert gaze, the smallest rock lizard, the patches of killer grass... May the wolves and lambs of Tassili slit each other's throats and devour each other in peace! Only one thing alerts his watchful eye: the anomaly!

This publication "Corpus" takes a particular form and offers a reading experience in several stages. First, by (re)reading Arzak le Arpenteur in its digital color version, starting with the image, with the dialogue or with both at the same time. In the second part, discover the very beautiful black and white sequel, without words, drawn in India ink and reworked in places on the computer. Finally, in the last part, archives and compiled research, visualize the ending with multiple threads of intrigue and outcomes.
