RE: the "Surprise" Sierra thinks most didn't see coming:

I'm going to guess it has to do with the demons showing up in Ardford. It's a callback to the minor "magic fields" quest, which you did and didn't really think about how they created, but Robin had some dialogue about the nature of high level magic and "superreal" phenomena. My speculation is that whoever summoned the demons to attack Tyna was responsible for the magic field disturbances during the conference-a result of straining magic fields by using extreme high power magic. It means there's an unknown party involved in events in Ardford.

Another off-the-wall theory is that it's a result of Varia, and her fate/luck is somehow warping magic fields around her. The demon attack on Tyna was not a conscious decision, but an intervention of "Destiny" to bring Tyna and Kalant into contact. It feels like a set-up because fate is setting people up.
