Wonder how well the Lantern Bearers will be integrated into the Inquisition when the time comes. Their structure is pretty different. All members theoretically equal, with no actual hierarchy. Which probably came about due to their origin and the paranoia against infiltration by the supernatural, adopting something of a cell structure. After all, you can't compromise all the Lantern Bearers at the same time if there's no one that actually knows about all of them in the first place. Which makes quite a bit of sense when you don't have the sheer amount of magic and crafting that Viserys' Inquisition has at its fingertips.
Also, man, Ryam seems like a pretty good person. I hope that he and others like him among the Maesters won't get caught up in any of the violence when Viserys takes over the Kingdoms in preparation for the coming Night.
