I'm not sure about the Blightlands as a name. The plague is particularly significant in Groam, but Groam is by no means one of the dominant or enlightened cultures in the area. On the contrary its a little backward. If there are to be dominant cultures in the region they are more likely to spring from Orvaelos, or the Steppe culture that Gamerprinter is putting together, form what we have seen so far, and these places, whose naming conventions are more likely to stick, are not significantly affected by the plague. Just my two cents.
