I also would like an Aetherlight comic book or graphic novel. Given how good the in-game art is, I would be expecting top-notch work there.
The storytelling would need to better than The Timekeeper’s Apprentice, though. TKA has some good points, but it’s not as good as the storytelling in the actual game. I think the Aetherlight team does best with said game, rather than side projects.
Another option would be like some web comics with like in-game hints or something. That would probably be better and really fun.
