Something really interesting just popped up in my head! Pegasi control the weather over Equestria, and also Everfree controls it's own weather! But something is off with every other race kingdom around Equestria! The changeling hive sits upon a desert wasteland! The yaks live in a snowy wasteland! The dragons live in a desert wasteland! The griffons live in a desert wasteland! Don't you see the pattern here?! The other creatures can't control the weather like the ponies do, and that's why they all live in lifeless wastelands! Most of them don't even grow crops!
The ponies are so afraid of these other creatures that they're not sharing their weather! What do you think about this? Don't you see that every other civilized race around Equestria has the same weather while the ponies in Equestria can control their own?
