Mary Janowski was one of the child survivors of the Starnes Exploration Party on Triacus in 2268. Seemingly unphased by the death of her parents, Mary was an unwilling follower of the entity Gorgan. She and the other children were coerced by Gorgan to take the USS Enterprise to Marcos XII, to spead the evil entity's persuasion. Mary spent most of her time on the bridge with Tommy Starnes and they together maintained control of the ship. (TOS: "And the Children Shall Lead")
