If you look at the map, then you can see that Equestria isn't a world. It's like a country, since the Yaks live just north of the Crystal mountains. There's a place for dragons, and a place for Griffons. I'm also positive that the Changelings were banished to the badlands. My only question is how many other villains were banished to the badlands... I know Tyrek and his brother were supposedly banished to the badlands. Since it shows it in the episode where he escapes. What confuses me is how all the villains are actually kept there. I know that Cerberus guards the area that Tyrek was kept, but is that in the mounatin? There really isn't anything known that keeps them there. Something I also want to know is where exactly the Changelings are from. Since Chrysalis said that Equestria has more love than any other place she'd been to. So how many villains are here? Which ones are here? and Why are they staying there?
