Gray Knight was the first level of knight, and given to a Teidowan who had successfully completed the Gray Jedi Knight Trials. A Gray Knight was the first level of knighthood among the Gray Jedi, essentially an introductory rank before becoming a full Knight. A Gray Knight could not go on missions alone, as they had to be accompanied by another Gray Jedi of the same rank, or higher. After two years of training and missions, a Gray Knight would be able to take the test to elevate from Gray Knight to the full title of knight, which was called Koawan.
