Dreadnoughts are death incarnate, towering war machines bearing powerful weapons to blast their foes, and lethal close combat weaponry cracking with deadly energies to tear them apart. Standing tree times the height of a man, Space Marine Dreadnoughts are amongst the oldest war machines fighting on the battlefields of the 41st millennium, with some dating back thousands of years to when the Emperor himself walked amongst his people. Each Chapter's Dreadnoughts are treasured relics, a tangible link to its past heritage, and are only awoken their slumber in the times os great need. Each Dreadnought contains a living, sentient being, and the pilots encased in its shell often have memories stretching back over many thousands of years.
