The Eighth Order was also known as the Hermit Order or the Kane Order.
As the Eighth Holy Spirit was the only Holy Spirit that had been promoted from a mortal, the Eighth Order paid more attention to the union of secularism and faith than the other parishes of the Holy Spirits Church. It emphasized the unity of the mortal and holiness.
As for the Eighth Order, it was divided into two factions—Divine Grace and Holy Seminary. The former emphasized the sanctity of the Eighth Holy Spirit and advocated for the Eighth Order to completely integrate into the Holy Spirits Church's system. At the very least, they didn't have to carry the title of hidden Holy Spirit.
