- Name: Anastasia Belladon
- Occupation: Imperial Noble
- Born: 269.M41
- Status: Resides in the Belladon Dynasty Palace in the upper spires of Hive Babelion on Tachion Primaris
- Background: Born into the main line of the Belladon Dynasty - a major family of the Nobility of Sector Deus - Anastasia lives a life of decadent luxury and power over those lower in society.
Anastasia Belladon's life was fairly typical for a noble, living in a large palace, feasting on the finest delicacies and having an extended life due to expensive rejuvination treatments. Until 332.M41, when she met Sergeant Lusmer of Larion Ursus' Honour Guard at a social gathering. Sergeant Lusmer became enamoured with Lady Anastasia, who reciprocated his feelings (on the surface at least). The pair entered a relationship and after a few months requested Chapter Master that they be married. Though genuinely considerate of Lusmer's emotions, Chapter Master would not allow the marriage to occur, concerned that Anastasia's motivations are not as pure as Lusmer believed.
In 355.M41 when brother Cagirates was recovered from the Babelion Underhives, he revealed the Anastasia was a witch who had entranced Lusmer with her powers - apparently on the order of Sector Lord Larion Ursus. When asked about his relative, Alderon Belladon said that he did not know Anastasia was a psyker and no official records state she is sanctioned, raising the serious concern that she is a rogue psyker.
