No, this is not another "Hwa Ryun is secretly a Ranker!" theory.
We don't know much about Hwa Ryun at the moment, but what we do know has sort of clicked together in my mind into a large picture. Hwa Ryun is part of the Red Witch Clan, a race of guides, sort of foils of the Silver Dwarves. We met her for the first time in the Crown game where she was already a part of FUG and in contact with Rachel. However, we immediately hit a snag right then and there.
Hwa Ryun has stated that she is just using FUG for her own purposes and her goal lies elsewhere. The mocking/joking tone she uses when she refers to Baam as "My god" (as compared to FUG's legitimate reverence to Slayers) also collaborates with this. But if she has not bought the doctrine of FUG then why had she joined it? Why was she in it before she ever met Baam and Rachel?
My theory is that she had foreknowledge about their appearing in the Tower, specifically Baam's appearance in the Tower.
To understand this, you must understand how the racial position of a guide works. Specifically, Guide, Gilahbi in Korean, just means "one who chooses and leads the way." Yu Han Sung describes them as "ones blessed by the Tower of all the paths within, to assist (a team) in its navigation, and, at times, are even able to foresee the future and change it." It can be said that a Guide has extreme analytic skills and are able to examine people and routes to determine the best course of action. However, rarely, they are said to be able to actually see and change the future.
I think it is for this second reason that Hwa Ryun is well known among Silver Dwarves despite only being a Regular. If she made several predictions in the past, as a child, before joining FUG, and they all came true despite her never seeing the places or people she predicted, it would seem remarkable to both the Red Witch Clan and the Silver Dwarves as Guides seem to rely on their observation and analysis skills and not true supernatural foresight. This is how her beauty could be a plot point. There could be a rumor that there is a beautiful young girl in the Red Witch Clan who can actually see the future, and therefore Evan Edrock was surprised to see her because he recognized Hwa Ryun from the rumors.
This plays into why she joined FUG. She literally foresaw Baam before he entered the Tower and she saw what he did or could do afterwards. The man he could become. She didn't join FUG, then Baam and Rachel entered, FUG found out then asked her to guide them (Rachel first and then Baam from then on) but she joined FUG because she knew Baam and Rachel would enter, FUG would find out, and Rachel would betray Baam.
After all, let's imagine for a moment that Hwa Ryun hadn't joined FUG, that she was just another Regular on the Floor of Tests that Baam befriended. He and Rachel would still have entered, Rachel would still have seen him take the ball test, still have thought that he stole everything from her, still would have betrayed him to become the "heroine" of the story, and Baam still would have ended up in FUG's clutches after the betrayal but with no one on his side save Ha Jinsung - who would have been another stranger to him. Moreover, she would have gotten a ring and been another one of FUG's hostages. If she tried to do things afterwards, knowing through her foreknowledge that Baam was still alive, that would have tipped off FUG.
Instead, she entered FUG, became a Guide to it's Rankers, perhaps even told them that she knew two Irregulars would enter the Tower. That way when they got both under their thumb she could still stay by Baam's side, help him become stronger (physically and mentally) and see about cutting their (or at least his) ties with the criminal organization afterwards. If she has some larger goal outside of just getting Baam strong enough to survive the Tower that can be explored later in greater detail.
