Yeah, after taking some time and talking to major NPCs (Not just in Ul'dah) basically the Seed Seer and the Admiral has declared that the Warrior of Light is protect while within the borders of their lands. Also, the charter that allowed the Crystal Braves to operate within Gridania and Limsa appears to have been revoked, as they are no longer in those cities. Of course, it's also pointed out that you should stay away from dark allies, secluded areas, and other places where you could conveniently "vanish".
In Mor Dhona, the Domans pretty much say that anyone that messes with you there will be vanished.
In Ul'dah proper, the whole incident is being kept under wraps. All that's being said is the the sultana is gravely ill, the WoL and Scions had a hand in it. Of course, thanks to all the people that you helped, it's being taken with a grain of salt.
The Crimson Flames, who are loyal to Rhubhan, are trying to figure out a way to take the city back from the Monetarists, but want to figure a way to do it without Ul'dah plunging into civil war, more and likely causing the deaths of many innocents and wrecking the hell out of the city. It also why it's why you should continue supporting them. They're the non-corrupt side of Ul'dah's army, so keeping them supplied is a good idea, since the Monetarists probably aren't going to being giving them much in the way of anything, now. Straight up disbanding them would be overplaying their hand, but denying them resources? Sure thing.
The reason the Crystal Braves and Brass Blades just don't arrest you while strolling around Ul'dah is because people wouldn't stand for it, and civil war would likely break out over it. It's also in the Monetarists best interest to not have a civil war start. You can't make money if the city gets wrecked and a bunch of people die. Besides that, you have the backing of the Adventurer's Guild and Craft and Gather guilds if you got those to 50. That's a lot of powerful groups to piss off. Better if they can just make you disappear, which is why I wish S-E would add random assassination attacks while you're out in the boonies.
So the whole thing has become a political stalemate. No one dares to do anything because Ul'dah's become a powder keg ready to blow, and either due to loss of life/destruction of Ul'dah/loss of profit, no one wants that. This is why the WoL can walk freely.
As far as "I'ma white mage, I could have Esuna her!" She was already falling off her chair before the WoL realized something was wrong, and she was dead (or out, for those that think it didn't killer) before she hit the floor. Doubt that even the most quickdraw swiftcast esuna could have saved her.
As far as Rasing...well...when it comes to character deaths, storytelling has always trumped game mechanics in the Final Fantasy series. I mean, how many characters have died in the series could've been saved if you could just Raise them? Hell, by game mechanics, Nanamo should've just been warped back to whatever Aetheryte she was bound to.
Of course, this mess could just be avoided if there was a little blurb before you go into the Sultana's chamber saying "We need to confiscate your weapons" and then afterward Alph saying that he managed to snag them on his way out. In that case, the game mechanics actually works in the story's favor, because the character is completely reliant on his weapons for their powers, which
-would- make him/her completely powerless the whole time. Which now that I think about it, is probably why SE isn't keen on the idea on letting PUG/MNKs being able to fight bare handed.
