The Hierophant of Ninbolm governs Ninbolm
Amelar the Immaculate is known as the Hierophant of Constant Sorrow.
Those Brothers of the Spear who defied their Hierophant’s order to join the Temple Invisible were transformed by him or her into the wretches who call themselves the Temple of Alberon. He or she is presumably the precursor to the Unseen Hierophant.
