Ah, I apologize! I am Princess Celestia. [The slight rustle of feathers indicates Celestia briefly attempted to make a gesture in accompaniment with that statement, but then remembered it was audio...] My sister and I rule Equestria, but my residence is in Canterlot, a city some distance from Ponyville.
The problem here is the use of the term 'world'. If you look at Traverse Town, it is a town, not a planet, but we nonetheless call it a 'world' in the realm of sleep. Similarly, Ponyville is just one town in one country in one world, but here it is a 'world' we can travel to. So I am a resident of Equestria, but not of Ponyville.
