So I currently finished chapter II going Iorveth's path and somehow I must have missed something in the plot. The main conflict in this chapter is the battle between king Henselt of Kaedwen against Saskia's troops in Vergen. But, and that's the thing I found no explanation for, there's also a Nilfgaaridan camp around. Why that? I mean I know that the Emperor of the Nilfgaardian Empire is plotting in the background, but ingame I haven't noticed any explanation (or missed it). The camp seems to be there, nobody is questioning their presence.
What did I miss?
