I think that the Taken King dlc will take the the dark wolves from the trailer back to there kings house below (the basement) and take all of the secrets of the Skolas and will do the same with the dark below in the dlc after HoW and we as guardians have to help out at the end to fight back the The Dark Below and the House of Wolves when Oryx releases that hes son Crota was a jerk and wants to help us by showing us the backside of the enemy's that we have not seen before and we have to take them on and find the place where there mums that are giving birth to them and we got to kill there mums and end it all. https://www.youtube.com/watch?v=dQw4w9WgXcQ
