Praetors of Orpheus

The Praetors of Orpheus is a Loyalist Space Marines Chapter and a Second Founding or “Primogenitor” Successor Chapter of the Ultramarines. The Praetors of Orpheus’ understanding of Imperial science and technology is second only to that of the Tech-priests of the Adeptus Mechanicus itself. Many believe that the two organizations are tied by more than shared service in the Emperor’s name and that the Praetors have shared personnel and goals with the Mechanicus in the past.
