@Stabbey: I can understand that the divine order became more fanatic when the divine one died.
But what do you mean by "rise of the black ring"?
According to the wiki, the chaos demon was summoned by somebody (the black ring?). If this was not them, at least they existed in DD when they created Damien.
Or does rise mean getting stronger because they got their leader back (Damien returns from nemesis)
Also I do not understand how sourcerers fit in here:
In D:OS1 sourcerers where considered evil because the source of source

was corrupted by the void dragon. This had been solved at the end of D:OS1. Why does the divine order hunt sourcerers several thouthand years later? I still do not understand what is the difference betwenn source magic and "normal magic".
