Nechani
The Nechani are a race encountered in the Delta Quadrant by the USS Voyager in 2373. They are humanoids and are a spiritual people.
One of their most sacred shrines is managed by the Nechisti, an order of monks. The shrine itself was protected by a natural force field which could cause massive neural damage to anyone who attempted to cross it unprepared. The Nechisti knew the method of crossing the field but did not easily share it.
In 2373, Kes encountered the field and fell into a coma. Captain Janeway went through the Nechisti rituals in an effort to save her. After three days of grueling trials and exposure to a hallucinogenic toxin, the captain believed she had the answer. However, it was only when she abandoned her scientific approach and embraced a blind faith that she successfully penetrated the field and returned Kes to health. (VOY: "Sacred Ground")
The Nechani starship NSS Oracle's Tears, was encountered by the USS Rosenante in 2408 when they were captured by The Harvester.
