The order of monks who tend the sacred shrines of the Nechani and guard the ritual through which a petitioner may approach the ancestral spirits.
The Nechisti Order is the priesthood of the Nechani, a Delta Quadrant people who invite the Voyager crew to visit their world. The monks look after shrines that only they are allowed to enter, and they keep the details of their rites to themselves.
In Sacred Ground, Kes wanders into one of these shrines and is struck down by an energy field, falling into a coma. The Nechani magistrate explains that the spirits have punished her and that the monks cannot help, though an old tale tells of a king who pleaded for his son by undergoing the order's ritual.
Janeway claims the same right. A guide leads her through a series of trials, and three elderly figures in a waiting room push her to set aside her faith in scientific explanation before Kes can be saved.
