A planet at war with a neighbouring world of Vandor. Both worlds fight their war through proxies, men chosen from each world who duel to the death in a computer-simulated combat arena. Tarrant learns his brother Deeta had volunteered to fight for Teal in a recent battle, but Servalan has rigged the combat so a conventional war will be unleashed that could kill millions of people. The Federation will then step in and annex both worlds with a so-called "peacekeeping" force.[43]
