Trust me, you'll get your war soon. It is coming, without a doubt.
Yes soon the Qunari will again try to control the world and in those dark days it will be the blood of men that stunts the flow of Qunari influence upon the world.
Orlais, Nevarra, Antiva, The Free Marches, Perhaps others will unite and stand side by side and throw the horned giants back into the sea, armies will clash, cities will be destroyed and taken.
But Thedas will endure and it will be free.
Well as Free as Thedas ever was...but you all know what i mean.
