In the house of wolves I think we can finally kill her or her -blam!-ING BROTHER!!!
HER BEING THE QUEEN
-
So if the Queen falls that means we get house of wolves, by law of the fallen the queen is there kull so killing her gives us the right to control them. Maybe this can lead us to play as the fallen, they are the only race that can be playable I think. A fallen Guardian sounds cool to me and seeing a vanguard in the tower would be awesome.
