The greatest general the Astra Militarum has ever known, Macharius was a man possessed of fierce passions, unyielding piety, and one of the finest tactical minds that Humanity has ever produced. Born heir to the rulership of Donia, he was already a general in the Astra Militarum by his early 20s. While this appointment might have been due to his rank, he quickly proved more than worthy of it. He brought the Roxane Rebellion to a swift and decisive end, earning him the attention of the High Lords of Terra and seeing him named as heir to the Lord Commander Solar Philips, whom his forces had rescued. This position, which he would inherit when his predecessor was killed in action, granted the now Lord Commander Solar Macharius all the authority he needed to pursue his almost boundless ambitions.
