Thanks for the link on Nekron. The blogger's theory certainly sounds plausible. I could see GJ resurrecting him and making him over. I haven't been a deep follower of GL recently, but I have read Rebirth, Wanted: Hal Jordan, Secret Origins, and the Sinestro Corps War, courtesy of the local library. I like what GJ has done with Black Hand, but he still felt too small a villain for me to believe he is the main guy behind the Black Lanterns. Nekron would make more sense.
