Dian Fossey's Rain Slicker

Origin
Dian Fossey (1932-1985) was an American primatologist who is most known for her study of the mountain gorilla in their natural Rwandan habitat, and the public awareness she raised to their endangered status with her book, Gorillas in the Mist.

A former occupational therapist, Fossey's love for animals inspired her to travel to Africa on safari in 1963, a decision that would ultimately allow her to rub shoulders with Louis and Mary Leakey, well-known contemporary anthropologists. Her tenacity and interest in mountain gorillas impressed Louis Leakey, who three years later reconnected with Fossey and funded her research trip in Rwanda. Fossey's experience with autistic children as a therapist helped her connect with the gorillas, who had until that point only experienced human contact through poachers in the area. After two years of earning their trust, Fossey was able to interact with the gorillas closely, and began forming close relationships with them.

Fossey, like fellow Leakey-funded primatologists Jane Goodall and Birutė Galdikas, became a major figure in the natural sciences, contributing much to what we know about mountain gorillas, including vocalizations, social structures, diet, and band formation. Her dedication to the animals, however, earned her many enemies, as she sought to oppose the rampant poaching, tourism, and farming that encroached upon the non-enforced borders of the Virunga National Park where she worked.

On December 31, 1977, the body of one of Fossey's favorite gorillas, Digit, whom she had watched grow up, was discovered after having defended his troop from a group of poachers and their dogs. Digit had been beheaded and his hands hacked off for an ashtray. From this point on, Fossey became more reclusive, and abrasive with her employees and research students. Her tactics against poachers and local law enforcement became more aggressive as she handled opposition with a skillful sense of violence, humiliation, and superstition.

Nearly seven years later, Fossey was found murdered in her cabin, having been bludgeoned by a machete to the face. The perpetrator is still unknown, as are their motivations. She is buried alongside Digit, and other gorillas killed by poachers, at her research lab in the Virunga National Park.

Effects
Imbued with Fossey's heartbreak and outrage over the loss of Digit, when the slicker is worn it manifests emotional pain into large clouds of water vapour that can hide and obfuscate the surrounding area. If the pain is strong enough, the vapour will manifest into forms that can carry out the desires of the wearer, often appearing as extensions of their subconscious.

This artifact is at its most powerful when worn by someone who is single-mindedly emotionally compromised, and as such appears to limit the user's ability to calm down.
