After a few minutes, Promise says, "I think I've found a good place to put the gate you'll go through. It doesn't seem to be anywhere near the routes the Queen's vassals are using to fly around and if you drop straight down from it you'll land on a balcony that's usually unoccupied but leads to what I suspect are the Queen's sleeping chambers. I've spotted her; she had six vassals with her, which seems likely to be typical, but they may not be in the room with her when she sleeps because no one expects anyone to be able to make a gate like this. I should probably describe the Queen herself, I suppose you don't know what she looks like."
