343 has all but incorporated AFoA into the canon. Obviously, that's a good thing, because it's an incredible story and a beautifully drawn graphic novel.

So here's my question: Why hasn't it been made official?

Levi said 343 once contacted him about publishing it, so why did that fall through? Legal issues?

I feel like Canon Fodder could be a good place to finally incorporate this thing into the official canon, if only Microsoft would give Grim the clearance to do it.
