The Dark Nest is controlled by a former Nightsister named Lomi Plo, who became their Unseen Queen with her ability to become invisible by exploiting the doubts of inferiors . One of the Myrkr mission survivors, Alema Rar, attempted to plant seeds of doubt in Luke's mind by suggesting that his wife, Mara, may be somehow responsible for the death of his mother, Padmé Amidala, which he almost believes because of Mara's previous involvement as the Emperor's Hand . </P> <P> This allows Lomi to escape from Luke .
