Batbayar Khan
Batbayar Khan is the Captain of the White Scars Chapter's 4th Brotherhood and he led them against the Tau Empire in the Second Agrellan Campaign. However when their Homeworld, Chogoris, was invaded, Batbayar was ordered to go to its aid and his Brotherhood immediately withdrew from Agrellan. Unfortunately, a Warp Storm threw their Strike Cruiser, Northwind, off course and they emerged close to the Damocles Gulf. Before they could reenter the Warp, though, Batbayar was contacted by his Battle Brother and old friend, Nergui who was currently serving as a Deathwatch Captain on the Watch Station Picket's Watch[1a]. He informed Batbayar, that the Deathwatch needed the Khan's aid in destroying a Tau Empire Stormsurge facility on Proth, whose destruction would win great glory for the 4th Brotherhood. At first Batbayar refused, stating that Chogoris needed his Brotherhood's aid, and promised only to leave two of his squadrons to aid Nergui. This changed, however, after Nergui told him the Tau Commander Shadowsun, was at the facility - which immediately piqued his interest. Batbayar knew the White Scars' Master of the Hunt, Kor'sarro Khan, had sworn to kill Shadowsun, but had so far failed to do so in the battle for Agrellan.[1b]
The amount of personal glory he could win by killing the Tau Commander filled Batbayar's head, as well as the pleasing thought of presenting Shadowsun's head, to an angered and shamed Kor'sarro. The Khan also knew though, that Shadowsun's death would signal the end of Kor'sarro's hunt and he would be able to bring his 3rd Brotherhood to Chogoris' aid as well. All this immediately swayed Batbayar's opinion and he readily agreed to aid Nergui in the Deathwatch's mission[1b]. Together the Deathwatch and White Scars destroyed the Tau Empire facility, but Batbayar was enraged when he was not able to find Shadowsun during the battle. Though it was a great victory, it was not what Batbayar had been promised[1c] and 26 members of his Brotherhood lay dead at the Tau's hands[1d]. The Khan would confront Nergui about this and asked if the Tau Commander had made a fool of him, as she had Kor'sarro, by somehow escaping from their grasp. A guilt ridden Nergui instead admitted that he had lied to his old friend. Shadowsun had never been at the facility at all and the Watch Captain had knowingly lied to Batbayar, in order to ensure the Khan would aid in destroying the Stormsurge facility. A raged filled Batbayar then struck Nergui across the face and then walked back to his surviving Brotherhood, after telling the Watch Captain that he was no longer the Khan's Battle Brother or friend[1c]. Batbayar then immediately ordered the Brotherhood to gather their dead and to begin preparations to leave for Chogoris.[1d]
