Hey! So I don't know if this will be much help, but I really want to hit my five post minimum and it's one of the few things We actually did with my homebrew map. When my friend told me what he was looking for in a world, and what kind of campaign he was going to brew, the place names almost wrote themselves for me. To explain, while it is a legitimately made campaign, it is structured so it is full of tongue-in-cheek references to it being a game and has an interesting mix of humor and seriousness that is hard to explain if you do not know the DM. Therefore many of the place name, for instance the continents are Dankia and Memeius after the term Dank Memes, the DM's name is Dylan so the primary empire is Dylanium and the capital Dylanith, since he created the world. Clearly it is far from the most realistic or accurate way to name places, but I feel at least that they mirror the world well.
