History (as Sibur told Khushrenada13 and the other Corps soldiers)
Sibur was born in the year AC 181 in Germany, but he moved to Holland at early age. When Sibur was 12, Treize Khushrenada became the commander in chief of OZ. Inspired by the charismatic leader, Sibur joined OZ. There he became a Leo pilot in the same division as future Corps commander Khushrenada13 and he met Lucia Noin. The three became good friends.
When Treize Khushrenada resigned from OZ, Sibur sided with the Treize Faction. One day, the unit he was in was ambushed by Romefeller and almost completely destroyed. Sibur was the only one to survive the attack, but because of his injuries he couldn�t pilot mobile suits andparticipate in the military for a long time. This way, he was unable to fight in the Eve War.
Eventually he witnessed the new Romefeller Foundation�s rise to power and felt powerless since he couldn�t do a thing because of his injuries. But he heard about an organization that gave Romefeller quite some headaches. He didn�t know the name of the organization, but would later find out it was the old Khushrenada Corps. Once his injuries were healed he tried to contact the Corps, but he didn�t succeed and decided to continue his education.
However, not much later, he was contacted by his old comrade Lucia Noin, who had become a captain of the new Khushrenada Corps and she asked him to join the new Khushrenada Corps. He joined and was glad to meet both Lucia and Khushrenada13 again, which he hadn�t seen for over two years. He became a captain and although he hadn�t piloted a mobile suit for some years his piloting skills didn�t seem to have decreased. He proved to be a valuable asset to the Corps, as expected.
True history
Sibur was born in the year AC 181 as the oldest son of a wealthy German family. The Diskets fled their duchy when it was attacked by the United Earth Sphere Alliance and moved to Holland where Sibur was sent to military academy. When Sibur was 12, Treize Khushrenada became the commander in chief of OZ. Inspired by the charismatic leader Sibur quit military academy to join OZ. There he became a soldier in the same division as future Corps commander Khushrenada13 and he met Lucia Noin. The three became good friends.
When Treize Khushrenada resigned from OZ, Sibur sided with the Treize Faction. Because his family had always supported the ideals of the Romefeller Foundation, that decision had caused him to fall from their favor. One day, the unit he was in was ambushed by Romefeller and almost completely destroyed. Sibur was the only one to survive the attack, was captured and returned to his family. The next three years he slightly won back his family�s favor again. When the new Khushrenada Corps started to retaliate against Romefeller, Sibur was ordered by his family to spy on the Corps and destroy it from within. Afraid to fall further from favor, he decided to follow these orders.
When he was pondering on how to get inside the Corps, he was suddenly contacted by his old OZ comrade Lucia Noin, who had become a captain of the new Khushrenada Corps and asked him to join the Corps. Without hesitation Sibur joined and used his cover as Corps captain to undermine the organization. With a couple of undercover Romefeller technicians and the Foundation�s vast fortune he built the Neptune Gundam to back up Romefeller in the final attack on the Corps. However, because he was treated with much respect at the Corps he began to doubt the path he was taking.
