death and the capture of Louis IX marked an end to the seventh crusade. He was succeeded as Grand Master by Renaud de Vichiers. Chronicler De Sonnac was the first Grand Master to formally record the intricacies of the Templar hierarchy. He added this to existing archives, codified them and stored them in a safe place so that the order would have accurate records in future years. It is certainly ironic that, for a man responsible for creating the order's most in-depth records, there is no indication of when he was born. In fiction Guillaume de Sonnac is a prominent character in Crusades, a graphic novel by Izu, Alex Nikolavitch, and Zhang Xiaoyu, published by Les Humanoïdes Associés, in which he is show as a power hungry plotter.
