Great Myrtonian Fantasy - Template map and Political Map

So, remember that Worldbuilding project I mentioned in my previous post which I announced to all of you on my birthday?

Well, I realized I forgot to give it a name, so it's Great Myrtonian Fantasy!

Funny story of how I got that, when I Was drafting this entire world years ago, the placeholder name was just "Generic Modern Fantasy" shortened to GMF (Also can be read as Genetically Modified Food), but GMF grew on me, so I thought of ways to keep it, "Great" and "Fantasy" were instant autofills, but what do I put in the middle? And then I got it, based off the Myrtle plant, Myrtonia. Great Myrtonian Fantasy.

Anyways! Here's that improved map! This is the template (Note, Atlantica's Political Borders are already outlined due to its unique circumstance of being completely underwater):

And here's a political map!
