A term used by the Vibranni to describe "two-spirits", or an individual who gives up the gender role assigned at birth to pursue a life as the opposite.
Male Vibranni that are Verkhnemchelov have the right to become Vidvoya (the term specifically for male to female changes) Males who do not exhibit the extra joint are not able to become Vidvoya. The permission to change is only granted by tribal elders. If a male tries to be a Vidvoya without permission, the individual is severely punished.
Female Vibranni that are "two spirited" are called Vidvoye.
Any that prefer to be genderless are called Vidvoy.
The Vibranni believe that the spirits enter the child, causing the child to maintain the characteristics of that spirit.
