with critical and commercial success while the book itself suffered from censorship enacted by DC starting with the new creative team's very first issue and continuing into Millar-written spin-off mini-series focusing on the team's former leader Jenny Sparks. As a result, the creators repeatedly requested a "Suggested for Mature Readers" label for the series but the idea was vetoed by then-Publisher of DC Comics Paul Levitz. Meanwhile, DC published a "lost" Superman Adventures script by Millar to capitalize on his newfound success, while Millar himself considered a move from his native Scotland to the United States, deliberating between staff position offers made by Wildstorm and DC Comics' main competitor Marvel. In June 2000, Marvel announced that Millar will join its then-upcoming "Ultimate" line of comics as the writer on Ultimate X-Men, since Brian Michael Bendis, who was previously attached to the series, decided to focus his attention on the inaugural "Ultimate" launch of the Spider-Man title. The line, designed to simplify and streamline the company's long-running fictional continuity for mainstream audiences, was met with instant critical and commercial success and, soon after the launch of Ultimate X-Men, Millar announced that he had signed a two-year contract for a staff writing position at Marvel. As part of the deal, Millar and his family relocated to New York. In November 2000, Millar and Quitely announced their plans to leave The Authority after the third story arc, which was supposed to run in issues #22–25 (cover-dated March–June 2001) if the series was to maintain a monthly schedule. However, soon after the first issue of the arc was published, it was announced that Quitely had signed an exclusive contract with Marvel and would therefore leave the title earlier than planned. Wildstorm assigned Art Adams to finish the last issues and hired writer Tom Peyer and artist Dustin Nguyen to create another four-issue story arc that would fill the publishing gap while Adams worked on his portion of the series. Then, following the 11 September 2001 attacks, Wildstorm decided to postpone the release of the remaining three issues and further edit the completed but not yet released work for sensitive content, which eventually drove Adams away from the title. The Authority #29, Millar's last issue on the series, was published with art by Gary Erskine and the cover date of July 2002. Another Millar-written The Authority spin-off, a one-shot story tentatively titled Apollo/Midnighter, was announced
