So I was reading the grimoire cards and came across something pretty interesting. The fallen all have "houses", house of devils, winter, kings.. Etc. So obviously the new dlc is about a new house of fallen. But in the grimoire, it says the house of wolves is the fallen house that is commanded by the queen of the reef. So possible missions in the reef, maybe a little more light will be shed on the back ground of the queen and the house of wolves?? Just something i found interesting.
