The style is found in Profantasy's "Cartographer's Annual, Volume 7" 2013, and is available from the same page that you provided the link to in your first post. The annuals are add-ons to CC3. That is to say that they are additional to the main piece of software, but they are bursting at the seems with hundreds of different styles, and well worth the cost
Make sure that you have registered CC3/CC3+ on the Profantasy page and created your account there before you buy an annual, so that the annual can be added to your list of purchased software, and will appear in your downloads page for you to collect.
While you are on Profantasy's page, you might like to have a quick look at the forum there, where a search can often provide all the information you will need if you get a bit stuck.
