When he graduated, Severus with the help of his grandparents managed to get his mastery in potions in less than two years. He joined the death eaters, in order to become a spy for the ministry since Voldemort was looking for a potion master. His grandparents were proud and happy, when he worked for the auror department as an auror. They were dismayed, when he started to work as a spy, but they still supported him. His grandparents lived a quiet life until they were killed by Ryan and the other death eaters, in order to avenge his former uncle, who committed suicide, because he never got over the betrayal of his own parents. Severus was furious, what his cousin had done, but he waited until Ryan was arrested, but it was tempting to kill him, when he declared himself as Lord Prince. Severus had to seal his grandparents" wills under their order after they died since the eldery couple didn't want Ryan to find out about them. They told him until the war ended, Severus wasn't allowed to open the wills. When the war came to an end and Voldemort was defeated by John Potter and at the same time Ryan Prince was arrested, Severus opened the wills and the wills were read with him and his close friend, Amelia Bones, who had acted as his witness. In the will, it was stated that he was the next Lord Prince and that he had inherited the Prince family fortune and all the other vaults that were assoicated with the title. At the end, the will stated that his grandparents are hereby disowning Ryan from the family due to his betrayal against the family and the fact that they were deeply disappointed in him. The disownment took place, when James Potter and Sirius Black wanted to start to investigate the Prince family with the arrest of Ryan Prince, but it failed, when he was disowned and the Prince family had washed their hands from Ryan much to James" and Sirius" annoyance. Amelia was the one, who had stopped the investigation against the Prince family to the order's rage, and until this day, she was the proxy of the Prince family and she sealed the votes completely, so that no one could find out, who the new Lord Prince was. Severus still worked as a spy, but not as Dumbledore’s, no, but as Crouch’s and Amelia’s spy. During the war, Severus spied against Dumbledore and his order pretending to be the order’s spy by spying against the death eaters for the order. He gave up information to Amelia and Crouch first and asked them, what he was supposed to say to the order and they told him, what information, he was allowed to reveal and what not. He liked it, how it annoyed Dumbledore to no end that the DMLE knew more than him, when they were fighting against the death eaters. Amelia and Crouch also dismissed all of his charges since he was a ministry spy, when an order member tried to file an arrest and search warrant against him. It was painful for the order that every evidence, they filed against Severus was immediately dismissed. No one, not even Dumbledore, did know about the fact that he was a ministry spy and he smiled, when Severus had seen, how the aurors, who were members of the order apart from Moody, protested against Amelia's decision, but sadly for them, they were ignored. At the end of the war, Severus was given a full and blank immunity by Amelia Bones personally, who was the new head of the DMLE after Crouch fell from grace, and the arrest warrants against him were immediately dismissed to the order’s private fury.
