The sisters were young during the reign of the Elder Gods and old when Lothian was a mortal born. They have persisted longer and stronger than most any other god. The march of death is ever present, as the armies of the world class and litter the fields with the fallen dead or the aged wizen woman pass quietly at home in her bed. The dead pass from this world and the cycle of conflict and reverence for the sisters continue eternal. The priesthood of the Sisters is wrought with disparity and duality. Heiran represents the natural order of death that is visited on most of the mortal world. While Nareis represents the hastening of death, a knife murder in the night streets to kingdoms waging wars against each other. While they act through the subtle influnceing of mortal, their whispers or nudging chart the course of history. Heiran gaining the upper hand leads to years of peace while when Nareis inflames petty concerns exciting death, blood and ruin in her wake.
Priests of Heiran
The public face of the the Sisters and the Priesthood is Heiran with a temple, shrine, and clerics dedicated to the natural state of death. This helps the followers ease the passing of loved ones, assist with burials and protects the dead. The mortal clerics and followers focus on their duties and flock while remaining despairingly disconnected from the cosmic struggle of conflict between the Sisters. They are appalled by any that would imbue false life in the dead, crafting abominations of life is strictly forbidden. Clerics of Heiran are most commonly known as Shepards.
False life is an abomination to the dead
Clerics of the Heiran can be male or female and wear simple black robes with a white silk sash at their waist.
The official symbol of the Sisters are two female silhouette back to back with a skull missing the lower jawbone overlaid on their dresses. Each portion of the imagery is a duality of conflicting black and white representing the silent and ageless struggle between the sisters. Simpler more common holy symbols used by clerics range from a simple disk half black and half white to the same disk with a black and white skull. Once again this shows how the priest of Heiran show the colors and symbols of Nareis, yet never speak her name or acknowledge her.
The Red Stain
A few select mortals give voice to being priests of Nareis, even though they do it from the shadows without temple or flock. They are persecuted by the Empire and the Priests of Heiran. Some believe that necromancy is the natural evolution of death and of Nareis. If ever overheard the Priests of Heiran refer to the false priest as the Red Stain or the Stain never using the name of Nareis.
Temple & Shrine
Also known as the Pale Church, Pale Temples or Pale Shrines. It is said that the Pale Temples house the largest collection rites and rituals regarding funerary and burial customs within the empire.
Knight of Death
One unique piece of myth and lore places Lothian as a chosen of the sisters, caught at birth between their age old conflict. He is named a Knight of Death, on the path of The Sisters, his choices throughout life falling to one or the other. Ultimately when he was crucified his soul had swayed to Heiran and the natural order of death.
It is said that the followers of Castain were pawns of Nareis and Lothians rise to power marks one of Heirans greatest victories over her sister. Clerics of the Sisters will never comment on this, leaving this between the cosmic powers to wage at their the scale of their tables. This is fervently rejected by the The Church of Lothian as the darkest heresy and sure to draw the ire of the Church.
Priests of the Sisters tend to react in a variety of behavior when encountering Untouched . Untouched are those few unique races or individuals that may fall outside of Heirans touch, but are still subject to Nareis. A few example are sentient constructs such as warforged or certain souls touched by immorality. They are rumored to treat some elves in this manner as well as celestial touched mortals blessed with immortality.
Inspired by the short passage of Heiran and Nareis, evil sisters of death in the Ptolus City book. This is a departure from and expansion of that section. All of the Gods of Death in the Ptolus book are evil with the cavate to design any you need which seems like an oversight. Gods have a natural place in most D&D-ish fantasy settings and death has a natural place as well. So its easy to arrive at a non-evil god of death. To go one step furthur lets take the sisters and have them represent the conflicting duality of death. An excellent example is Aza Guilla, Goddess of Death, Lady of the Long Silence as seen in the Gentlemen Bastards series. Some easy Dungeons & Dragons non-evil examples are Kelemvor (Forgotten Realms), Wee Jas (Greyhawk), The Blood of Vol (Eberron), Anubis & Nephthys (Egyptian). Pathfinder starts off with few non-evil gods of death but opens the flood gates with later supplements.
