Porcupine Autumn

When summer comes to an end and autumn first arrives, the spikes of the Porcupine Moon are at their brightest. On clear nights, when there is little other light than the stars, the spike appear to have a faint purple outline. This happens but one night a year, a time that occurs exactly every 400 days, a standard year in Karenth and Els'tar.
During this night, the druids gather from all around to the Druid Circle of Karenth or to one of the smaller druid circles in the event they are not able to make it to Ironholm.
The Porcupine Autumn is a celebration of the circle of life. A time for reflection, and a time to enjoy the harvests and hard work of the proceeding two seasons. It is also a time to finalize plans for winter. Most of all it is a time of celebration for the druids, fey and natural world.
Normally the event occurs before Falltime, as crops are still being brought in for the next few weeks. Also, Porcupine Autumn is a celebration for the Druid Circle, and is not open to the public. Stories of the year are shared, drink imbibed, dancing to be had, and strange uncovered magics shared with the circle.
The end of the festival is a large circle dance, lasting close to an hour. Everyone is dressed in their heavy travelling robes. It is a highly choreographed event beginning with the newest members of the Circle dancing, and progressivly moving through to the older members, and all participate. At the end of the dance, everyone collapses, sleeping where they fall until morning.
