1. Page 13 states that the first Peacock Shrine is in the Cloister of Cerulean Languor. According to the map on page 16, the Cloister of Cerulean Languor is in areas B1-B3. However, the entries for areas B1, B2, and B3 contain no reference to a shrine (unless I missed it). Also, since each shrine is trapped if the incorrect rod is removed, I need to know what the trap is for the shrine in the Cloister of Cerulean Languor.
It seems as if the shrine list has a typo for the first shrine; the list (as you mentioned) says that the first shrine is the the Cloister of Cerulean Languor, but the shrine actually appears in the Glorious Approach, in area C5. It doesn't seem to be trapped, other than the effect listed in the shrine master list.
