the origional aiel used the term in a Robert Jordan book as well, but in a more wordful way
"You killed some one, you are dead to me and the rest of the True Aeil......Turn away from me i wish not to see that face, my son had a face like yours, but alas he is dead to me?
1. I hate you, you hate me. I killed you and you're dead now. with a great big splash and bodies on the floor, no more you cause you're dead.
A death note to all who live on this earth.
