I'd like for it to be noted that the air in Hive cities isn't just dirty, it's filtered, enhanced with additives, and absolutely choking with toxic chemicals and pollutants. Those people are wearing gas masks for a reason. All the non 40k characters really should be having more trouble with the air than they're having right now, especially Mat, who apparently isn't bothered with air that's capable of killing you if you breathe it unprotected for long enough.

I'll make a point of Thane attaching his gas mask
