Codex: Grey Knights (English)

The Grey Knights strike with overwhelming force – each a warrior mystic whose martial prowess is matched by his psychic and sorcerous might. Clad in warded plate of truesilver and adamantine, armed with crackling Nemesis force weapons and devastating psy-active firearms, they are all ruthless destroyers. It can be no other way, for this Chapter wages a war in utmost secrecy against the Dark Gods of Chaos to prevent the death of reality itself.
