I am just coming to AGOT and I think it's interesting!
Here is some questions about killing characters.
1. When we have to kill multiple characters, like losing a military challege with power 2 or some plots like kill everyone, can I choose the order to kill them in order to trigger some death responses or there is a canonical order to do this?
Also the same question for that among players: when everyone has to kill some characters, who is the first?
2. can not be killed: does this mean I can select him as a killing target but can not kill him or I cannot select him as a target? If it's the second one, when I lose a military challage, do I have to choose other character to kill? And what happens when I use the plot like valar morghulis?
