[Korra's face is set in serious mode. The reason? One of the new arrivals, and she's taking it upon herself to warn everyone about the threat he poses.]

Hello? If all of you can hear me, I have something very important to tell you all. There's a masked man that just arrived. He calls himself Amon, and he is very, very dangerous. He's a waterbender from my world and he also has the ability to bloodbend, even outside of the full moon. [She takes a deep breath as the video starts to twitch a little. It moves back as she sets it down against something, but it stills.]

If he tells you a story about wearing the mask because his face is burned, it's a lie. Any burn marks you see are painted on. His story about a firebender killing his family is also a lie. His brother is this jerk councilman, Tarrlok, back in Republic City. And his father was this criminal named Yakone. Amon's real name is Noatok.

I'm not sure if he'd be able to do it to anyone else, but the benders from the world I'm from need to be careful around him. He can take away our bending, but I don't know how to reverse it. Not yet. The rest of you, be careful and don't do anything stupid. I'll be the one to deal with him.

[And off the video goes.]
