Within Ustalav, Pharasma's faith is ubiquitous; Tar-Baphon sullied the land, and undead are a constant threat to mortals. To protect their kin, Pharasmins trained to fight undead, learning methods by which each can best be contained and destroyed. As necromancers took root, drawn to Tar-Baphon's legacy, these Pharasmins expanded their purview, learning to root out Necromancers, members of the Whispering Way, and victims of possession and mind control. Girded in off-white armor and robes, the group became known as the Ivory Reapers. Although they serve as sober defends of the living, their mysterious methods of divining which among the populace are secretly necromancers and heretics, and hunting them down, causes typical citizens to regard them with fear.
Since Tar-Baphon's return and the destruction of Lastwall (now known as The Gravelands), the Ivory Reapers redoubled their efforts. Their adherents are found questioning travelers and villagers as often as they're seen putting down roving undead.
