A quarterly publication, "Following Cerebus", followed in August 2004, featuring correspondence, essays, and previously unpublished artwork from Sim, as well as interviews with other comic writers and artists. Sim was rumored to have said that had he died or otherwise chosen not to complete "Cerebus" prior to issue 300, the remaining issues were to either consist of blank pages or Gerhard was to have drawn his backgrounds only, leaving Sim's contribution blank. It is not known if this plan was ever serious, since it was never put into effect. At the completion of the series, Sim directed that upon his and Gerhard's death, "Cerebus" would enter into the public domain. Effective 31 December 2006, Sim purchased Gerhard's share of the company. Sim has already granted a general license for other creators to use his characters in their own works, stating that he is trying to be consistent with his own appropriation of others' works. In early 2009, Sim launched the bimonthly series "Cerebus Archive". It was translated into Italian; and in 2011, "Church and State Vol. I" was published in Spanish. This first story arc, uniquely in this series, consists of one to three-issue storylines with only occasional back-references. Cerebus is introduced as an amoral barbarian mercenary, fighting (and betraying) for money and drinking it away. During his adventures, he encounters the warrior Pigts (whose religion reveres aardvarks) and the insane wizard Necross, who turns himself into a giant stone Thrunk (visually similar to Marvel Comics' The Thing). Most of the series' prominent characters are introduced (or at least mentioned) in these issues, including Elrod of Melvinbone (a parodic representation of Michael Moorcock's Elric of Melnibone), Lord Julius, a character based upon Groucho Marx, Artemis Roach (a.k.a. The Roach) and Jaka. The series takes a sharp change in direction with issue #20 which is the first of the "Mind Games" issues that are a feature of the comic and introduces the philosophical Suenteus Po and the ultra-matriarchial Cirinists. Cerebus comes to the wealthy city-state of Iest as the representative of Lord Julius's city-state of Palnu. He quickly finds himself enmeshed in the fast-paced world of high finance and politics, and comic tension is built through his ignorance of the "high society" machinations going on around him.
