Maybe the Dust storms'll be like the Cloud was in the Madre: Killer.
I mean, they could say something like "the sand in the storm rips at the flesh, peeling it from the bone of anyone stupid enough to get lost in them. Slowly wearing down the being until s/he/it is no more." :bolt:
Sounds unpleasant :cryvaultboy:
I posted this on a different topic but I reckon the locals there probably wear protective gear similar to Sand People, and if you wear that kind of outfit or a PA of some sort, you might become immune to environmental hazards.
