SpoilerFigured. I was thinking the "if none left alive...but at the same time Amber has a LOT to risk...an entire war in addition to the current war? It'd be VERY bad so she'll be quit hesitant to get involved having to balance Warden duties with not being a bitch and abandoning a child.
So she's HOPING she won't have to get involved and the others can handle it.
Edit: I know a wizard who started a war because of a situation like this :P
