I have a situation under control. I assure you, the Fire Nation *cannot* penetrate this wall. Many have tried to break through it. But none have succeeeded.
What about the Dragon of the West? He got in.
W-well technically, yes. But he was quickly expunged. Nevertheless, that's why the city is called "Ba Sing Se." It's the impenetrable city. They don't call it "Na Sing Se."
That mean penetrable city.
