Shortly after the release of "Ptolus", which Cook has often described as the culmination of his original ambitions for Malhavoc, he announced that he would be focusing on writing fiction and other unspecified forms of creative work, rather than role-playing games, for the foreseeable future. White Wolf and Goodman Games announced his final RPG books. "Monte Cook's World of Darkness", his own take on White Wolf's modern horror setting, was released at Gen Con 2007. From Goodman Games is "Dungeon Crawl Classics: #50, Vault of the Iron Overlord", which was also targeted for the same Gen Con release.
