A central hub of Arconan society, the Grand Nest served as the primary nest situated within a clearing on Cona. It was around this nest that the Arcona constructed their individual nests. The Arcona ensured that family nests remained within a 20 kilometer radius of the Grand Nest. Gatherings took place at the Grand Nest every twenty days, presided over by a Nest Leader, a male Arconan elected by the community to serve as their leader.
