Dirty Dozen: The Imperial Grand Admirals is an article that was written by Daniel Wallace together with Abel G. Peña specifically for Star Wars Gamer magazine. This article contained both biographical information and roleplaying game stats regarding the Grand Admirals serving the Galactic Empire. Following the discontinuation of Gamer, Wallace and Peña reworked a substantial portion of the original article to create Who's Who: Imperial Grand Admirals, which appeared in Star Wars Insider 66.
