Rikku WOULD love the Cloister of Trials puzzles, haha. Also I never did think about how Kinoc and Co. got into the guardians' waiting room outside the Chamber of the Fayth so fast (or got Yuna's party out of it after they got arrested). The Via Infinito is a very tidy and plausible explanation. During that puzzle in the game we can just see Tidus but I always picture the entire party crowded together onto that one little platform, with assorted expressions of delight, resignation, and terror.

Those are some intriguing hints at the circumstances surrounding Auron's being dishonorably discharged from the warrior monks, as well.

The surroundings of this chapter were vividly described; I could hear a kind of background soundtrack of crackling flames and crashing architecture in the back of my mind while I was reading.
