Lacy Devist was a Human female. In 19 ABY, she became the wife of Carib Devist.
Lacy probably did not realize that her spouse was secretly a clone of Soontir Fel, a Baron. Further, he was an operative of Imperial Intelligence dispatched to Pakrik Minor by Grand Admiral Thrawn. Carib and Lacy had two children together: a son named Daberin, and a daughter named Keena Devist.
