A Tavnian man married to Lwaxana Troi, who pursues her to Deep Space 9 in the episode The Muse to claim their unborn son under his people's customs.
Jeyal is a Tavnian who appears in the fourth-season episode The Muse. Lwaxana Troi married him and became pregnant, and only then learned that Tavnian tradition requires boys to be taken from their mothers at birth and raised solely among men until they are sixteen.
Unwilling to give up her child, Lwaxana flees to Deep Space 9 and asks Odo for refuge. Jeyal follows, courteous but immovable, and insists on his rights as her husband.
Odo finds a way out in Tavnian law, under which a marriage ends if the wife takes another husband, provided the groom sincerely declares why he wishes to wed her. He marries Lwaxana in front of Jeyal and speaks so movingly of what she has meant to him that Jeyal accepts the ceremony as genuine and leaves without the child.
