The Revenant (TSW)  

Amongst the ranks of the living dead, the Revenant holds a special place. No mere reanimated corpse, the Revenant has formed from the restless fragments of those who, in life, did great evil. Devious and clever, the Revenants serve no master, no greater plan or intelligent design. All they crave is misery, pestilence, agony and death. They feed on terror and pain, and their presence is always an omen of impending doom.

Imbued with strong occult magic, they are able to change themselves into creatures associated with death and darkness: ravens, rats, spiders and worms. They can leap huge distances, crawl upside down at great speeds, and squeeze themselves through the narrowest of spaces. Revenants typically use poison and disease as weapons against the innocent, and their weapons - often twin knives - can cause hideous infections in those without protection against dark magic.

Drawn to areas where a disaster - natural or manmade - is imminent, Revenants have been instrumental in spreading pest and plague throughout history; from the bubonic plague and smallpox in Europe, to flu and typhus pandemics across Asia. In 1905, they arrived in the United States, carried across the ocean aboard freighter ships, hiding as rats and crows in the cargo. They have recently been spotted on an island off the coast of Maine, where, it is rumored, a great evil stirs.

The Revenant is one of the most terrifying creatures of the secret world. Not easily defeated, they are known to reform from the smallest fragments, and their poisoned blood and dark minds infect everything around them with their eldritch disease.
