XIII (Thirteen) is a Belgian graphic novel series about an amnesiac who seeks to discover his past. It was created by writer Jean Van Hamme and artist William Vance. XIII was released in 1984 as a serial in the popular Spirou magazine, and it was popular among Spirou readers. The first three episodes were released as a single hardcover volume by Dargaud the same year. XIII was originally written in French, and it was translated into several languages, including Dutch, German, Polish, Tamil, Serbo-Croatian, and Italian.
Jean Van Hamme has declared that he will not continue to write the series, but William Vance is interested in continuing it with another writer. Yves Sente, who had already taken over writing Thorgal from Van Hamme, was interested to continue the series. He was contacted by William Vance and said he'd propose a story to Van Hamme, but no agreement has been reached yet. Ever since October 2008, Sente has authored volume 20 of the comic series (Mayflower Day), published in late 2011, alongside Youri Jigounov.
