The central part of the courtyard, with the areas reserved for the displays, is clearly the heart of the festival. A keen observer might note that the spaces reserved for the exhibits representing the Great Clans are arranged so that the order more or less resembles their positions in Rokugan - with the Court to the east, where the sun would rise each day. For one walking in from the court chamber, therefore, the artwork representing the Crab Clan would therefore be to the left, while that of the Phoenix and Dragon would be to the right. The space reserved for the Crane lies to the left as well, not that far from the Crab - perhaps an unconscious effect of the Yasuki's experience of the Crane as being "just around the corner". The area for monks and imperials is roughly at the centre, more or less close to the Court - where one would expect to find Otosan Uchi, although since the distances are far from following perfect scale, one could also easily argue that this central area would be Kyuden Ikoma instead.
Although the central part is clearly the focus of the night, a few tables and sitting areas were left alongside the paths and close to the pond, so that those who might want a place for a (slightly) more reserved conversation, or just a spot to sit down and relax, might find one.
Servants will be found walking through the area offering tea, sake, rice balls, sweets and other similar refreshments. A few tables with such refreshments are also placed at strategic points among the exhibits (Lion and Crane rice plantations? Crab sake and tea? Who knows...) so one doesn't necessarily have to wait for a servant if they want something. That such tables also tend to lead to conversations may or may not have contributed to their being included.
Masaki is dressed in the kimono she wore to court the previous day, a gradient from dark slate gray to almost white with a white, black and blue koi pattern in the front and two large black and white carps interlaced in a yin-yang symbol over a sunset red circle. After having clearly spent some time seeing to the arrangements, she seems to be rather busy doing final adjustments and talking to her clansmates at the exhibit representing the Phoenix clan.
That notwithstanding, as the one who proposed the event, she will make sure to set aside some time to greet and welcome everyone who arrives for the festival with a warm smile.
