Following the announcement at Emerald City Comic Con that Valiant's next major event will be titled "Book of Death," the publisher has followed up at this weekend's Wondercon with a series of macabre teaser images featuring Bloodshot by Rafa Sandoval, Ninjak by Kano, X-O Manowar by Cary Nord, and Harbinger by Raul Allen, each overlaid with the prophetic, Biblical phrase "So let it be written, so let it be done."
