The Order of Herpa the Mace is a clerical order of the Hierarchy of the Eternal Flame. The order is open to both sexes, although the overwhelming majority of priests have been male since the schism of 714 TR. It sponsors the fighting order of the Red Shadows of Herpa.

The Order is limited to western Hârn. It is most active in the Rethem but also operates within the Thardic Republic. Orderial headquarters are in Golotha. The order also maintains five other major temples in Rethem (at Ithiko Menekai, Senun, Shostim, and Techen) and three in Tharda (in Coranan, Moleryn, and Telen). The Coranan temple is covert and has only a handful of priests and even fewer Terahni from the Red Shadows of Herpa.

The Senesharil of the order is Andraz Enald Enald. He is also the Viriahn of the order's Golotha temple. The order has two Markithai, one of whom is the Viriahn of the Menekai temple, the other of whom is the Aperahki of the Golothan temple.
