During the day Vrok'sha are forced to walk as men, anatomically undistinguishable from humans.
When the Vrok’sha fall asleep at night, they undergo a radical morphological change. The extent of this change is unknown, however, as Vrok’sha are completely invisible to the naked eye in this state. After this transformation, the Vrok'sha become active again.
Based on the remains of its prey, it can be safely said that the Vrok'sha are three things:
Large, strong, and savage.
Vrok'sha release pheromones during February to attract other Vrok'sha of the opposite sex. The gestation period is 9 months, which helps it blend even better within the human populace.
Vrok'sha in their human forms grow at the same rate as humans, although the same cannot be said for their true forms. These forms grow to their full size in three years, possessing a savage cunning not present in their human forms. Subsequent years only sharpen its intellect.
Vrok'sha prefer boreal forests and northern cities as their habitats, as it allows them to use their surroundings to hide and ambush their prey. Typically, Vrok'sha live in close proximity to both of these habitats, as cities afford protection for their human form and the forest provides sustenance. Cities are also home to so many prey items just walking about...
Vrok'sha in their true forms are strictly carnivorous, requiring enormous amounts of flesh to fuel their restless existence. They hunt large mammals, such as Deer, Elk, Bison, Moose, Humans, and sometimes even Bears. Vrok'sha are ambush predators, using their stealth and incredible strength to take down even the largest of prey items.
In their human forms, the Vrok'sha imitate the human social structure. Vrok'sha in their true forms lead solitary lives, only seeking out other Vrok'sha for the purpose of mating.
The Vrok'sha posses a cunning intelligence that matches or exceeds those of the ordinary human, using said intellect to place themselves in positions of power and to set up traps for their prey. Sometimes, these situations are one and the same.
After all, many people go missing in Blackwood at night...
Vrok'sha hunt using a combination of heat-sensing pits, sound, and smell, allowing them to hunt even in the deepest of winter snows.
Some information on how they differ from humans in social and cultural ways would be nice to see. The article could also benefit quite heavily from an image of what the Vrok'sha look like in their real form.
Thanks for the feedback! Unsure how I would depict the Vrok’sha, since they are invisible. Predator style blurring maybe?
