Kala (The Keys of Marinus)

Kala was a citizen of Millennius and the wife of Aydan.

Biography
Kala, Aydan and Eyesen conspired to steal one of the keys to the Conscience of Marinus, hoping to sell it. After Aydan's part in the plot was revealed, she shot him so he would not reveal the names of his accomplices. She kidnapped Susan to cover up the crime, and forced her to call Barbara Wright on an Arbitan telephone

Barbara exposed her when Kala was confronted and already knew Susan was a hostage; as she could not have known that Susan was missing, Barbara deduced that Kala was somehow involved. When the First Doctor exposed Eyesen, he and Kala confessed everything. (TV: The Keys of Marinus)
