This is the Imperial Knight Codex.
The amazing art features an awe-inspiring Imperial Knight, towering above the battlefield as it leads a host of Space Marines into battle. The Knight, a massive war machine of the Adeptus Mechanicus, stands in its full majesty, clad in thick ceramite plating adorned with the iconography of the Imperium. Its armaments include a colossal battle cannon on its left arm and a massive chainsword on its right, both designed to obliterate enemies ranging from infantry to tanks. The Knight’s heraldry is proudly displayed on its shoulder, symbolizing the noble house or forge world it serves, while the armored cockpit reveals the pilot’s grim visage, directing the titan with precision and fury.
Below the Knight, a disciplined phalanx of Ultramarines advances, their bolters ready as they march through the war-torn landscape. The fiery explosions and swirling dust of battle fill the air, as the Space Marines, undeterred by the chaos around them, fight under the shadow of the towering war machine. This image exemplifies the might of the Imperium, where human soldiers and machines of ancient power unite to wage war against the countless threats of the galaxy. The combination of the imposing Knight and the steadfast Space Marines paints a picture of an unstoppable force advancing in the Emperor’s name.
