Agrovan Seven

Agrovan Seven was a planet inhabited by the Agrovans. Two groups of Agrovans, the Strykes and the Marat, were at war with each other and had been for over a thousand years. By the time the Seventh Doctor and Ace arrived on Agrovan Seven it had been declared a non-intervention site by the Time Lords. Someone had given the Strykes a Gallifreyan virus to use against the Marats, and the Doctor wanted to stop it spreading. They met a Marat, who took them to the Marats infected by the Strykes' new bioweapon. The Doctor then met with Doctor Treykan and gave her the antidote to the plague. (COMIC: The Forgotten)
