Golden Moon Festival

Two moons float in the sky over the Sundered Lands. The larger has a regular orbit, while the smaller moon has an irregular orbit and swings widely around the world and the larger moon. In late summer, both moons are full simultaneously over a three-day period. When the weather is clear they both appear to take on a golden sheen.
Bajapur, the largest and greatest city in the Sundered Lands, is a city of commerce and wealth where gold is the single most important thing to be desired and strived for. When the two moons are gold in the sky overhead, it is seen as an extremely auspicious sign and the three-day Golden Moon Festival runs for the entire time the moons are visible. It is considered the best time of the year to embark on new business ventures, and the entire population from lowest beggar to highest noble eats their fill of Moon Cakes, small round sweet pastries which are coloured yellow-gold. The source of the colour varies with the wealth of the one creating it: from an egg glaze and careful baking for the Moon Cakes eaten by poor people, through saffron and even gilding with pure gold.
If the sky is overcast or the moons are concealed for any reason during the period of the Golden Moon, it is considered an inauspicious sign and a portent of ill luck or trouble for the coming year. Newly-signed contracts and business ventures may often be cancelled without any default clause being enacted, as both parties will agree it is for the best as obviously the venture was doomed to fail.
When the Gold Moons are visible, however, the entire city is awash in yellow light from dusk to dawn, as a sea of yellow paper lanterns fills the streets. Everyone will wear some variety of yellow in their clothing, and it is considered lucky to be generous to others, especially those worse-off than yourself, so that your generosity will be returned through the coming year. Beggars will often receive new clothes and full meals during the time of the festival.
