We don't know what's on the other side. It could be the fade, another continent, or maybe another reality. All we know is that Morrigan considers it to be a safe place to hide her child and train him for whatever is to come.
DA2 sets the stage for the big change to come, but we don't get many answers. DA3 is likely to explain more. We also don't know if Morrigan or her son will show up.
He would be in his teens or early 20s by DA3, so it's possible.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
