Just the awoken. Maybe some fallen still loyal to the queen. But I think the entire fleet fighting oryx is just made up of awoken. It's been hinted at in grimiore for awhile on how powerful the awoken truly are. We just finally get to see it. Just as a frame of reference: ~certain awoken go under a ritual in which they can open a window in time to see the future. ~certain awoken can actually turn into crows. ~Awoken have these huge machines of war called harbingers. Not much lore about them. But considering the queen took on the house of wolves at their full strength to keep them from coming to twilight gap and the reef is still around i'd say they are pretty dang powerful.
