A small hand-held device used by Chakotay's people to enter the trance of a vision quest without drugs, kept in his medicine bundle aboard Voyager.
The akoonah is a flat electronic device on which the user rests a hand while meditating. It induces the altered state needed for a vision quest, replacing the psychoactive herbs that Chakotay's ancestors used. Chakotay keeps one in his medicine bundle together with a stone and a blackbird's wing.
In the Voyager episode The Cloud he uses it to guide Janeway on a quest to meet her animal guide. B'Elanna Torres mentions that she once tried the same and attempted to kill hers.
The device returns in several later stories, notably The Fight, in which Chakotay uses it to make contact with aliens in chaotic space, and when he seeks guidance from the spirit of his father.
