"Ka-Katara…you saved me." The boy said, the girl known as Katara started to cry, the bison moaned and gained more altitude and they soon disappeared.
-Back in the catacomb-
"They got away because of you old man. Father won't be so happy to hear this." Azula said, she was talking to the old man now trapped in crystals. The agents she called "Dai Li" were standing behind her with their arms behind their backs.
"Uncle, why'd you help them? They are the enemy." The boy known as Zuko said. The old man he called uncle looked at him in disgust before speaking.
"Zuko, look at you now, moments ago you despised Azula, you wanted to best her, and now you're working for her? I let them escape because it was the right thing to do. Now look-"
"Enough old man. Little Zu-Zu has chosen his destiny, when he gets home to the fire nation; Father will see him as a hero for killing the Avatar. We finally have all the necessary preparations to overthrow the Earth King, now that the Avatar is finished." Azula continued to speak to the Dai Li agents, giving them orders on what to do with the old man and to capture the Earth King. Zuko looked over the scene; his uncle hadn't looked at him at all, except when he yelled at him. Some of the Dai Li had gone to do Azula's bidding. Zuko noticed a dark portal opening, he walked over to investigate. When he got close enough to spy on the portal, a boy in a dark cloak adorned with silver chains stepped out.
"*sigh* ya'know, it's bad enough I was woken up for this stupid mission, but to go to a world I didn't even know existed? That's pushing it. Gexo, what's takin' so long eh? You've walked through the Lanes Between hundreds of times." Said the boy, he had long silver hair that covered his right eye, which were a blood red. One fang showed on his mouth, seems that it would stay out. He was calling to a shorter boy, shorter than the first at least, he too wore a dark cloak adorned with the same chains, he had bright blue hair, it reminded Zuko of ice, but near his left eye it was bright red, this reminded him of fire.
"Shut it Caxe, you know how I get uncomfortable travelling these lanes. Ok, we're s'posed to locate someone the locals call "The Avatar"."
"The what? Who? What's an Avatar?" said the silver haired boy the second one called Caxe.
"These two are increasingly strange, what do they need the Avatar for?" Zuko thought to himself, he heard the other boy Caxe called Gexo explaining who the Avatar was.
