The ancient and venerable Land Raider has served the Adeptus Astartes since its earliest beginnings, and many variants and patterns are recorded in the data-stacks of Mars. Adepts of the hallowed Adeptus Mechanicus collectively refer to the oldest of these as the ‘Proteus’ patterns, and examples of these mighty armoured vehicles that survive into the dark days of the 41st Millennium are held in the highest regard, war-relics beyond compare to the Chapters that possess them.
