There is something to be said about the orcish lens of CR4 and allegory vs metaphor. I have been trying and failing to say it for the last half hour. What I will say is this:
This is a story being told predominantly by white artists but has been framed in such a way that the lens through which we view the story is highly racialized. (We focus on the legacy of an orcish freedom fighter, in an orcish city, culminating the first chapter with a play about orcish history, liberating previously enslaved orcs from an unjust after life.) This is, in my opinion, a value neutral thing to be happening. But I do think it demands an audience that engages with that reality. And thinks about, not just the value of the lens, but also the potential disconnect between the lens and the creators. Ultimately, CR4 isn't just going to say something about race, it's going to say something about how left-leaning, white Americans, in collaboration with people of color, certainly, but definitely dominating the space, think about race.
This is not me saying "be on the lookout for mistakes to get mad about." What I am saying is that there is a rich vein for analysis here, that looks not just at what the story is saying and how, but also where the story's ideology and execution might be in conflict. Also, for all his proclamations of allegory, Brennan is almost certainly looking for the grace of metaphor
