Varlik
From Tardis Wiki, the free Doctor Who reference
Varlik was a Swampie chief on Delta III. He helped Rohm-Dutt kidnap Romana I.
After Kroll killed Mensch, Varlik began to doubt Kroll. Ranquin later suspected him of freeing the Fourth Doctor, Romana and Rohm-Dutt, as Varlik had thought they should die from the first of the Seven Holy Rituals, not the seventh. He later took part in the attack on the methane refinery. (TV: The Power of Kroll)
