Nasgard

Colonel Nasgard was an officer in the Kaled military and the younger brother of Tashek, the husband of Lady Calcula, and the father of Yarvell and Davros (the latter not by blood). His family was a prominent and distinguished one with a long line of military service. He favored strict discipline at all times, going as far as to execute soldiers for displays of cowardice, including the son of Tutor Magrantine. Years of fighting in Skaro's poisoned battlefields adversely affected Nasgard's health; he was sterile after Yarvell was born, and by the time she was 18 he had deteriorated to the point where Captain Brogan felt he had to report him to headquarters. Having been relieved of his duties, Nasgard requested the newly-promoted Major Brogan to shoot him, giving him an honourable death on the battlefield, but the Major refused and instead escorted the Colonel home to his family. After arriving there, Nasgard strongly objected to Davros's desire to become a scientist and insisted that he join the military as per family tradition. Lady Calcula, seeing her husband as a danger to her son, planted a bomb that killed him and Tashek, who told Nasgard that he was not Davros's biological father minutes before their deaths.

In Nasgard's will, the family finances were held in trust under Davros's name, and his wife and daughter were forbidden access to it until Davros got married. Lady Calcula hoped to get these terms overturned. (BFD: Purity)
