Chapter 1: The Black Dot

A/N: This is my first fanfic, so I'm not quite sure what to do. But anyways, I decided to make an avatar/Doctor who fanfic. I'm sorry if it's terrible, but here it goes.

EDITED: 9/2/13

VERRRRRM VERRRRRRM VERRRRRRRRRRM! SPLASH!

"Doctor! What was that?" yelled Amy Pond over the roar of the TARDIS.

"Something fell in the pool." The Doctor replied, not looking up from the controls. Then his head snapped around to stare at Amy. "I'm surprised that you even heard it. The TARDIS's engines should have drowned the sound out."

"So? I heard something fall in the pool, and you don't even care." She replied, slightly miffed that the doctor wasn't taking what she said seriously.

"Amy, I do care. It's just that the TARDIS's alarms haven't gone off, so it can't be anything hostile. She would know if the life form that fell in the pool was one of the many creatures in this universe that want to kill me." He said, as though that answered everything.

Amy however, had one last thing to throw at the doctor that even he hadn't thought of. "Doctor, how is it that someone appeared on your TARDIS while the TARDIS was in flight!"

"Errmm, good point." He said uneasily. "I'll put her into a time hover so that nothing can get us while we go, investigate." He finished with a flourish, belaying his own uneasiness about what had happened. How had someone gotten on the TARDIS? After what happened with Donna—NO! Not going to go back to one of my greatest mistakes. After the incident, I made it so that hureon molecules weren't able to get on the TARDIS. Who could have that type of power to get through her shields?

In Ba Sing Se…

At the Jasmine Dragon, the best tea shop around…

Iro was serving tea, Sokka was attempting to paint a painting, Toph was cracking blind jokes, Aang and Katara were having their first real moment after the war, when Zuko noticed something Sokka's painting.

"Sokka, what is that?" Zuko said, pointing at the small dark spot in the middle of the painting.

"What, that? Its just ink splatter." He spluttered.

"Really? Then why is it getting bigger?"

And it was getting bigger. But not getting bigger in the way that normal ink spots do. From Zuko's vantage point, it looked like the ink was reaching out, or maybe it was drawing itself in. It certainly looked that way. Aang, Katara, and Toph were definitely not that close to the spot before. He was not the only one to notice this either. Iro saw it just as it touched Aang.

CRACK!

"Aan—"Katara started to shout, but was cut off by another CRACK!

Iro noticed this. He saw that the image of Katara had just touched the black dot.

Meanwhile, Zuko and Sokka were arguing about the spot. Finally, Zuko said that it ruined the painting. Toph chose that moment to cut in and say "Well, I think it looks wonderf—" CRACK

And Toph disappeared right in front of everyone. Iro looked at the painting, and saw that Toph had touched the Black Dot as well, and she was quickly fading. What did this mean? And who was next?

A/N: Well, I re-wrote this chapter because I felt that the one that I wrote first did not go into enough detail nor did it provide necessary background knowledge about the event(s) leading up to the main plot.
