Water Spirits

The Supernatural Book of Monsters, Spirits, Demons and Ghouls mentions several Water Spirits in a journal entry from John's Journal:

Yodyanoy

• Russian
• Appearance: old man, skin freckled with scales, green beard (tangled with underwater plants)
• lives in sunken ships, whirlpools, etc.

The Yodyanoy may drown people, but may also protect fisherman if they dedicate their first catch to him. His servant or concubine is often the Rusalki.

John mentions he heard of Yodyanoy from hunters in Alaska but never saw one.

Rusalki

• women spirits (children or adults), who died in water (suicide or homicide)
• the adult version of these spirits are like Sirens; they lure sailors to a wet grave by seducing them with their song
• they might have vampiric qualities and vanish when their deaths are avenged
• they might be killed if you keep them out of the water for as long as their hair dries

Nix

The Germanic nix combines attributes of the two above creatures. John describes the nix as usually male and handsome. The nix plays music to seduce his target - like the Banshee, the nix might also warn of impending death.

John once encountered a nix in Pickney, Michigan - he used a Black Shuck as a sacrifice. ^BoM

Kelpie - Each Usige

A nix might appear as a horse called Bäckahästen - see celtic legends of the Kelpie. Kelpies appear near rivers and try to drown their riders. Another horse connected to water is the Each Usige, which can be ridden safely as long as it's not near water. Then it devours the rider, leaving only his liver behind.

In Massachusetts (Quabblin Reservoir) John worked an Each Usige case. ^BoM

Mannegishi

• native American
• lives in rivers, plays deadly jokes

John tracked down and defeated a Manneqishi in Minnesota.^BoM
