Aanung-an

Aanung-ans, sometimes called the occulted dead, are rare undead creatures that rise from the corpses of those who died while performing vile and malignant occult rituals. Rising as gangly, emaciated corpses attired in ritual trappings, aanung-ans wield obscure lore in service to unknowable agendas. Some scholars theorize that aanung-ans are somehow linked to one another and are attempting to enact a galaxywide ritual, though none agree on their final goal. Conjecture runs from summoning an eldritch horror from beyond space and time to snuffing out all life in the blink of an eye.
While aanung-ans are almost always solitary, rumors persist of individual aanung-ans raising small cabals of zombies to function as bodyguards and servants. Such aanung-ans are likely very powerful spellcasters with sinister schemes.
