This is a great story about how some people have to fix things in the aftermath of something they did that may change the world fundamentally, if not destroy it. With that description it sounds very similar to Ellis’s earlier webcomic (with Paul Duffield), Freak Angels.
Which is a fair enough assessment, though the triggering event in this case is a combination of AI, the internet, and old magic; as opposed to the psychic powers in the older work. Ellis has deeply embedded the “start late” advice often given to aspiring authors. Both of the works under discussion, and some of his others, start long after the events that set their plots in motion.
It can be a very effective device. We get to know characters who already know each other, and the past events are revealed gradually, through conversation and flashbacks. And the fact that the protagonists don’t at first fully understand what they did means that we learn along with them.
This is great, but the only frustrating thing is that these three volumes — comprising fifteen issues of the comic — are to date all that there is. I don’t know if they plan to continue it, but the last issue came out in November, and the story is far from over. Googling has not so far revealed the answer to this.
