Perfect. The rebel army and Earth Kingdom citizens have left Omashu. That only leaves a few of my most trusted advisors and servants. Kei-Bei (my leading advisor) is in Ba-Sing-Se. When the time comes, he will also be of use. But for now, it is time to strike the governor and his forces with such brute force that he will not know what hit him.
Aang, I sense that he has finally mastered Earthbending, and with the Blind Bandit too, impressive. He's in Ba-Sing-Se. Kei-Bei should have found him by now…can't ponder on events in the capital. I must do what I can now. I have two firebenders watching me. I cackle mischievously, but the guards take no notice, they're used to it!
I roll my tongue within my mouth, and sent a message to my advisors and servants, whom are also prisoners. Everything is set it is working perfectly. I used a little trick I learned from little Toph Bei-Fong. She's a very interesting little girl, yes, and she taught me the most important trick of all. I have been able to see and sense the Earth, but never see the landscape and humans, or irregularities on the surface. Toph taught me this trick in our few hours alone when the Bei-Fong family visited.
I sense wood in place, building new Fire Nation buildings. I sense Earth Kingdom buildings that are perfect as weapons. I send another message to my advisors: Now! All of a sudden, chaos ensues within "New Ozai." Fire Nation buildings collapse, Earth Kingdom buildings turn into boulders, and fly straight into Fire Nation soldiers. The governor's throne collapses, and the governor himself is now being transported to the dungeon on an Earth cart.
I break free of this weak wooden coffin, do they really expect this to hold me in. My advisors and I bust down the guards, and broke through the metal cages, yet another trick I learned from the Blind Bandit. (A/N I know Toph didn't learn this trick until she was in Ba-Sing-Se, so she had no way to teach this to Bumi, but whatever)
We were now on the loose. The entire city was our plaything. We could do whatever we wanted with this place, it was our dollhouse. Within a half-hour, the city had been surrendered back into the hands of King Bumi.
King Bumi, ah, you're a mad genius.
