Mraize mentioned how Helaran Davar had sought out the skybreakers and from the in world Words of Radiance This act of great villainy went beyond the impudence which had hitherto been ascribed to the orders; as the fighting was particularly intense at this time, many attributed this act to a sense of inherent betrayal; and after they withdrew, about two thousand made assault upon them, destroying much of the membership; but this was only nine of the ten, as one said they would not abandon their arms and flee, but instead entertained great subterfuge at the expense of the other nine. —From Words of Radiance, chapter 38, page 20 Pay extra attention to the line "but this was only nine of the ten, as one said they would not abandon their arms and flee, but instead entertained great subterfuge at the expense of the other nine." This leads me to believe that the skybreakers were the order that hid based on the existence of Nale's underlings and how Helaran apparently tried to find them.
And if the skybreakers are still around that would mean Nale has a LOT of people who can help him.
