It doesn't really make sense but if they're meant to be NPCs then I can't think of any other answer (besides possibly Leveva's grandfather since he wears the hat and she doesn't). I didn't think they were doing eight-man content for trusts yet though, and they didn't mention making it solo.
Can't say I'm going to miss it being a roulette trial, if it's going.
Also, the picture switching on the special site is obnoxiously fast. No time at all to study the picture before it gets snatched away from you.
