Antari system
From Tardis Wiki, the free Doctor Who reference
The Antari system was a binary planetary system containing the worlds Antari Two and Antari Three. While one account stated the Master tried to start a war there, (PROSE: First Frontier) another stated that he succeeded, having arranged a "particularly bloody little war" that he considered entertaining until it degenerated into savage butchery. Needing a rapid escape, the Master found the nearest Kitling and fled to the Cheetah Planet. (PROSE: Survival)
