It occurs to me that it might be a good idea to drop in the option for folks to read more about the setting, if they're interested. This is by no means "required reading" to understand the campaign, but if you'd like to learn a little more about the world, below is the setting primer I wrote up to pass along to players. It includes rundowns of all the particular races, oddities of classes in the setting, as well as quick summaries of major regions and nations. If you're not in the mood to do homework, feel free to skip past this.
No complete map of the setting exists yet, mostly because there are a bunch of countries that haven't even been named yet.
