The Festival of the Spirits was a time of celebration within the House of the Spirit Walkers.
Once held every fifty years, the House festival later commemorated the naming of each new successor to the sitting Prophet or Prophetess, and took place nine years into the emcumbent Prophet's tenure. Another festival was held upon the succession of the heir as the new Prophet of the House (eighteen years later).
Festival of Spirits was marked by several public rituals, games, arena events, and other activities in Hashan.
