"For as long as anyone could remember, the people of Veschke have lived in fear of fiends—spirits of wild places and volatile forces, agents of the fell lord Sokar, god of death..." Need I say more?
~The Lost Mythologies of Tamoreh: Book I~"Beware the thing that calls itself a spirit, faer or fiend. Pay them no tithe or tribute; accept no flattery or favor. No matter what they say, there is only one thing they truly seek: to enthrall your soul.”
Such great attention to world-building.
