Vader Down hasn't released yet though. Vader #11 comes out tomorrow, as does Shattered Empire #4 (the final issue).
There are about 5 to 6 ongoing Star Wars comics in current canon right now. You'll have to be a bit more specific to which one.EDIT: Just read it through that shitty water mark. Why don't they just make it part of the Darth Vader comic series instead?
