The Lost Souls - Wings of fire [OLD]

It's a peaceful day in the ice kingdom. Then, you here it. A scream. You walk out side and see everyone running around. Then you see a black nightwing making them turn as grey as he was. When he's done, he goes up to you and doesn't do anything to you. He was saving you for last. All the other tribes are in danger. It's your job to see what's making this nightwing go crazy, and stop it.
