Gravel returns with a super-size launch issue and an all-new monthly series! Mike Wolfer has worked on every issue of Gravel to date, and he's back to his black magic ways, joined by artist Gabriel Rearte who is conjuring stunning pages! This #0 is a perfect starting place for new readers, with a self-contained story and a huge what-has-come-before summary of all the previous Gravel issues. After dismantling the aristocratic, magical hierarchy of England and surviving a war against a blood-thirsty serial killer, William Gravel disappeared. But even a man who can walk through walls cannot escape Combat Magic-fueled assassins. And he's not happy about it. Written by long-time Warren Ellis collaborator MIKE WOLFER, GRAVEL: COMBAT MAGICIAN presents a fresh starting point for new readers to enter the world of ultra-violent black magic.
