Hello,

I'm trying to find the name of a sci fi series that was introduced as a comic book and then went on to be a regular text book series. I can't recall too much about it other than it was released prior to 2008 (though I don't know how prior). I think it might have been either Vertigo, Wildstorm, Image, Dark Horse or ONI Press but I could be wrong. I just remember the publisher had the first issue available as a free preview online sometime between 2006 and 2008.

I can't remember a lot about the plot, only that it was taking place on multiple planets.

Any help would be appreciated.
