We learnt in WaT that there have been Skybreaker dissenters who disagreed with Nale's leadership. Their leader, Dillid, seems to have left with some others at an unspecified point in time.
In The Lost Metal, the Ghostbloods put out a call for some special assets to help Steris in evacuating Luthadel, and people think that the people that arrive might be Skybreakers, as they seem to be able to fly and ask whether the sinking of ships is legal. But Brandon has suggested in this wob that they might not be Skybreakers as no radiants other than Hoid has gotten off Roshar by this point.
I'm tempted to believe that the people we saw are related to these Skybreaker dissenters, which might expain why they left Roshar for some other legal calling/framework to work for. It still doesn't answer why they seem to fly but I wonder if the fact that Highspren can leave the radiant bond willingly has anything to do with it, or if the dissenters were offworld already and then when Retribution formed and spren could leave, the Highspren somehow caught up with the dissenters again, granting them powers but being what we would typical call the "Radiant Order of the Skybreakers". The whole time dilation and timeline of Mistborn Era 2 relative to WaT might scupper this though.
Any thoughts?

Are the Coinshots that helped Steris with getting people out of the flood zone, and who seemed rather concerned with whether she was following the law, actually Skybreakers?

Ah, hehehehehe. So, we'll just leave that one. So, how about this. At this point in continuity, a Skybreaker could not easily get off of Roshar. In fact, by this point in continuity, I believe (you can't hold me to this one too much) the only Radiant who's managed to get off of Roshar and maintain powers is Hoid. I believe that's the case. Hoid is weird. He also has lots of knowledge. He used a specific method to get... yeah, anyway.
Don't hold me to that, but I think by this point he is the first to get out of system. Off-world doesn't really count because you can go to Braize or Ashyn.
