Ryland's Steel warband is killed during the map meta and story instances. That should make him a gladium, right? Or does his high rank somehow protect him and at least allows him to immediately recruit new members and rebuild the warband? Is there any canon material about such a situation?
So, assuming he is a gladium, how does his future look?
On the one side there's Bangar. He has already displayed with General Soulkeeper, that he is willing to ignore the gladium status if it suits him. He may do the same to Ryland - or treat him accordingly, maybe even just outright kill or ban him for "being such a failure".
But I'm more interested in the legions. With Smodur's kitten move, I think Ryland has nothing to return to. Even if he was willing to defect from the frost legion and even if the Charr were forgiving him for being in league with Bangar in the first place, he would still be an outcast. This can't look like an option to him.
Thus I think he can't be rescued any more and that he will not survive Ice Brood Saga.
Just to mention them: The Olmakhan let Rox, also a gladium, join. They could become a new home for him, too, but I don't think he would fit in well.
