The Feast of Suffitiel (SUF-it-EE-el)

In the Marran faith, Suffitiel is the angel associated with the moon. It is said to dwell within the lunar sphere (though most just know it as the sky) and there is division among the clergy over whether the lunar sphere is in fact Suffitiel itself or merely its creation in which it dwells. The moon is said to be the enormous silvery eye of the angel, set to watch over the world on God's behalf and tell Him of everything it sees. When Suffitiel is wide awake, the moon is full and bright, but the angel grows tired from its demanding task, and its eyes grow heavy until, with the new moon (Marran Blindesaugen, "Blind Eye"), it falls asleep for a time. Also known as the Angel of Vigilance, Suffitiel is commonly sworn by in oaths, so that should the oathmaker break their agreement God Himself is sure to hear of it.
The Feast of Suffitiel is held after the harvest, when the harvest moon has lit the nights enough to bring in the crops, to both celebrate the successful harvest and thank God for it, and to thank the angel for its aid. It is a communal event, celebrated by communities coming together and each contributing part of their harvest to the feast, and is held after sunset under the full moon following the completion of the harvest so that it is conducted in full sight of Suffitiel. Depending on the year, this may mean that the feast is actually held several weeks later, or the very next day.

Traditions

The feast is set up during the day by the clergy - this may be the monks of a monastery where one is local, but is more usually the local priest and whatever help he can hire or find - and begins when the moon is visible in the sky. Traditionally, the feast is held outside, and beyond city boundaries, normally surrounded by farmland, but village greens and other open spaces are also common.
Everyone who attends is expected to contribute some kind of food, though families whose harvest has been meagre are often given it as gifts by neighbours beforehand, which is handed over to the local priest or whatever clergyman is present. It will be prepared by volunteers, or in richer areas by the clergyman's servants. The feast begins with the community gathering at an important communal space - typically the church, though village greens or town markets are also used - where the local priest leads them in prayer. Afterwards, led by the priest (or most senior clergyman, if there are several present), the group proceeds to where the feast has been arranged.
Prayers are once again held, thanking the angel for its efforts, and then the feast begins. Once the food is gone, dancing, drinking and other entertainments begin, and continue long into the night. The feast is a time for communities to come together, and so business arrangements, marriages and contentious issues are often worked out at this time. Exchange of gifts, particularly handmade items, has become part of events as well. At a personal level, it is considered a good time for making personal resolutions as it is believed that any made in the full sight of Suffitiel are particularly strong and likely to be achieved. These resolutions do not need to be made public, though any who wish to may ask a priest in attendance to hear theirs and give their blessing.
