A Praesidium Shield is a unique piece of wargear utilised exclusively by the Adeptus Custodes, the elite guardians of the Emperor of Mankind. These formidable shields were first developed sometime during the Unification Wars in the 29th Millennium. They were the ornate precursors to the later Storm Shields utilised by the Legiones Astartes, and millennia later, their counterparts of the Adeptus Astartes in the 41st Millennium. A Praesidium Shield is forged from all but indestructible layered Ceramite and resilient alloys reinforced with built-in energy field generators.
Dreadnought Praesidium Shield
Essentially a scaled-up version of the prototype energy field-reinforced battle shield carried by the Sentinel Guard of the Legio Custodes, the Dreadnought Praesidium Shield makes the Contemptor-Galatus Dreadnought a truly formidable defensive element in any Legio Custodes battleline; a bulwark upon which the strongest shock attack might break and shatter.
