Doing so allowed John Sheridan and Jeffrey Sinclair to take the White Star back in time, and ensure that Babylon 4 entered the temporal rift and wound up 1,000 years in the past as was its destiny. Sinclair rode the station into the past, and became the Minbari leader Valen. Once Sheridan and the White Star arrived back in the present, Draal closed the rift so that no one else would become trapped in there. After the Vorlons and the Shadows left the galaxy, President Morgan Clark began a propaganda war against Babylon 5 and its crew. In order to counter this propaganda, Sheridan and Ivanova decided to broadcast their own reports on the atrocities of the Clark regime from the station's War Room. Because of the great distance from Babylon 5 to Earth, Ivanova enlists the assistance of Draal and the Great Machine to provide the massive power needed to enhance the broadcast signal across the divide. Dukhat was portrayed by Reiner Schöne. He was first mentioned in the episode "Soul Hunter". His only appearances were in the movie "" and in the episode "Atonement" as flashbacks. Dukhat was the leader of the Minbari Grey Council when he was first introduced in the film "". The Minbari considered him one of their greatest leaders, second only to the legendary Valen. "In The Beginning" reveals Dukhat as Delenn's mentor, and her eventual sponsor into the Grey Council, even though Dukhat belonged to the Warrior Caste and Delenn to the Religious Caste. Dukhat's administration of the Council was marked by growing fears of the reemergence of the ancient enemy of the Minbari, The Shadows. Many in the Gray Council refused to consider the possibility of the Shadows' return. In defiance, Dukhat ordered that the Council travel directly to the planet Z'ha'dum to investigate the rumors more closely. It was on this voyage that the Minbari first encountered humans. This first contact ended disastrously for both sides. The Minbari Warrior Caste soldiers who crewed the Council's flagship approached the Earth fleet with open gunports, a traditional gesture of respect. Realizing that humans would have no knowledge of this tradition, Dukhat ordered the gunports closed, but it was too late. Since the Earth ships could not jump away (due to an accidental side effect of the powerful Minbari scanners, which prevented Earth jump engines from working) and the human fleet commander was known to handle first contact situations rather badly, the humans believed that the Minbari were about to attack; they misinterpreted the Minbari gesture and opened fire.
