In the Chaos Wastes I added a few provinces, mostly just to add Zanbaijin, which is featured in the Thamurkhan book (which I didn't read, not a lore buff and all my info comes from wiki and Warhammer maps I found). The peninsula of Ind is changed in a similar fashion, with inland jungle provinces where the Tiger Beastmen would be largely concentrated. I also added some forested highlands because it was missing from the old map and I really wanted a wilder part within Cathay. The biggest change I made was Cathay, I wanted to add some steppes between the Great Maw and Cathay proper. If people really want to all you have to do is look at a map of the region's real world equivalent and purposely misspell some stuff or find a goth teen (do they still exist?) and ask them to come up with some edgy names. Unless it's naming stuff but hey, can't have it all. But if you're doing it do it properly I guess. I redesigned the eastern regions, they were pretty low effort last time because they're unlikely to appear and if they do would probably look very different from what I come up with. As it wasn't clear for some on reddit last time, brown are mountains, light green forests, dark green swamps and gold deserts.
