The Order of the Eight Demons is an all-female-clerical order of the Hierarchy of the Eternal Flame in the Church of Agrik sponsoring the all male fighting order, the Order of the Cohorts of Gashang.

The Order of the Eight Demons is limited to western Hârn. It is active in both the Thardic Republic and the Kingdom of Rethem, but its main power base is in Tharda. The order's headquarters is in Shiran (Tharda). The order also operates temples in Coranan (Thardic Republic), Geshtei (Thardic Republic), Themeson Keep (on the contested Tharda-Rethem border), and Golotha (Rethem). It also maintains a number of small chapels and shrines in and around Themeson.

The Senesharil of the order is Merele of Kantar, who is considered extremely sadistic, cruel, and ruthless even by other Agrikans. She is also the Viriahn of the order's Shiran temple. The order's Markitha is Karel of Delvanau. She resides at Gerdel, near Themeson and oversees the Rethemi branch of the order.
