Saeculum Aureum

The Saeculum Aureum is the earliest recorded period of history of the newly created Hammer Guard Space Marine Chapter and the feats of their legendary first Dominum Custodem (Chapter Master).

History
The earliest records the Hammer Guard have kept, before the opening of the secret vault under The Anvil, was about the time known as the Saeculum Aureum. This time period revolves around the Chapter's personal figure of legend, Dominum Custodem Augustus Eudoxius, and his time leading the chapter. During his reign as Dominum Custodem, the Hammer Guard experienced a time of honor and victorious battle, with him leading at the forefront. But what really made him legend was the Caedem Crusade, when he led the Chapter into the forefront of the fighting, cracking open fortress worlds and crushing the forces of the Archenemy. Even as he died he advanced the crusade, bringing the chapter honor and a hint of redemption. He was slain upon the world Caedem Primus, sacrificing himself to banish the Bloodthirster Kale'malum. With his death marked the end of this time, but also a step closer on the chapter's path to redemption.
