Warhammer 40K Grey Knights

The Grey Knights in Warhammer 40,000 are an elite order of Space Marines dedicated solely to combating the daemonic forces of Chaos. They are known as the Emperor's Daemon Hunters and are chosen from among the most virtuous and psychic-attuned Space Marines. Clad in silver armor and wielding powerful psychic abilities, each Grey Knight is a formidable warrior against the Warp-spawned horrors. They possess specialized anti-daemonic weaponry and are steeped in secretive rituals and lore to protect the Imperium from the most insidious threats of Chaos.
