Wang. The Adventures of Pvt. Wang Fire.
The Adventures of Pvt. Wang Fire is a novel written by Wang some years after the Hundred Years' War. Originally a private in the Fire Nation army during that war, he managed to remain in the army through the purges of Yiwen-Boar because of his loyalty to Firelord Zuko and his devotion to world peace. He retired after attaining the rank of colonel and became a calligrapher. During this time, he began work on this novel.
It is said that he was inspired by a tale in which Avatar Aang enrolled in a Fire Nation school during the War. According to this tale, Avatar Aang so thoroughly displeased the headmaster that he was required to bring his parents for an interview within a few days of enrolling. Not able to bring his true parents, he brought Katara and Sokka—later Chief of the united Southern Water Tribe—instead. Sokka took on the name "Wang Fire" for this interview, whence the name of Wang's character.
The premise of the novel is that Sokka, in an attempt to learn more about the Fire Nation army, disguises himself as Wang Fire and enlists in the army. He suffers through army training and undergoes many adventures while desperately trying to keep his identity secret. Near the end, he tries to escape; however, he is caught just as he returns to the Avatar and his friends. "Private Fire" manages to convince his commanding officer that he has actually uncovered a band of rebels, and fakes a heroic death.
The Adventures circulated only in unpublished manuscripts for about fifty years after Wang's death. Eventually a copy reached the hands of Chief Kulik, eldest son of Chief Sokka, who found it so amusing that he tracked down Wang's granddaughter and convinced her to have it published. His foreword, in which he claims that "there is no essential difference between [his] father and the Wang Fire of this novel", is famous for the ending line "To Wang Fire!". The Adventures was an instant hit, and is now considered one of the greatest pieces of satire ever written.
