Okay, this is a problem, so I'm just dumping the information here now.
1: The Courtyard is a subsection of the carnival away from the central courtyards (where the large tent is), actually pretty deep in and surrounded by a wall. There is currently an incredible amount of mist (more of a fog) concentrated in it, hence the light that Lucifer is using. I guess that wasn't very clear before, and I apologize for that. Also, the mist cannot leave the courtyard, so don't worry about that.
2: There is nothing to fight but a magical equivalent of a neurotoxin in the courtyard right now, just so you know as you retreat. Monsters will become available to fight, but not until certain triggers have been activated. There are none that are currently relevant here. Check back later when it opens up again.
3. The story/encounter trigger you are looking for is in the tent. I have been trying to direct everyone there, but that didn't work, so I'm telling you now. You have already activated everything you can use in the courtyard at this time and anything further is only going to be harmful.
10 points from Gryffindor for missing/killing off(?) one of the first important story points so quickly, but you get a bonus for stepping up the character introductions and bringing up extra information using a crisis. Nicely done, I will be keeping these notes for future effects.
Also, one person actually hit all of the story points they were meant to find, so congratulations to them. You'll get to see the significance of this shortly; we're about to start the first real chapter now that the intro is pretty much out of the way.
Any other questions?
