The rituals of the Mortuary Cult were laboriously inscribed upon vellum scrolls imbued with power, from which the priests would read during long and arduous ceremonies. As these ceremonies neared their culmination, the scrolls would crumble to dust, the power within them consumed by the unfolding magic.
When the Mortuary Cult raised temples in distant lands and excavated great tombs beneath far-off mountains, entire libraries of these scrolls were sealed away, only to be forgotten with the decline of Nehekhara's power. With Settra's invasion of the Border Princes and his vast host's glorious victories, the priests of the Mortuary Cult have been afforded ample opportunity to reclaim many of their lost temples and libraries hidden deep within the mountains of the Vaults.
