"The universe is not like a puzzle-box that you can take apart and put back together again and so solve its secrets. It is a shifting, uncertain thing which changes as you consider it, which is changed by the very act of observation. A powerful man is not a man who dissects the universe like a puzzle box, examining it piece by piece and measuring each piece with scientific precision. A powerful man has only to look upon the universe to change it."

— Techno-Magos Gaelos

"Tell them ruin has come to their world,
Death, despair and red war...
Tell them their hopes and pride have come to nothing,
Tell them their empty whispers fall upon deaf ears
their gods are dead,
human reason has killed them,
Tell them the Angels of Death have come,
Tell them nothing can save them now."

— Attr. Perturabo, Primarch of the Iron Warriors
