At the Grand Duke's Palace...
Dean Frey von Gregory led the intruder who broke into the First Military Imperial School to kidnap Jace Green, the illegitimate son of the Imperium's current ruler. After learning of the child's lineage, the original Grand Marshal brought him here from an abandoned star to the Imperium Main Capital.
At the time, the Grand Marshal intended to use this child as a bargaining chip against his younger brother. After all, this is the child of his younger brother and his adored wife. The current Emperor despises his current Queen and concubines. He had carefully concealed the existence of that child, who would have imagined that the world's two protagonists would be reborn at this time, and that the original Grand Marshal would be replaced by the God of Void. Many things changed in the future as a result of such circumstances.
