[WH40K] Why is our emperor special? I am only a child, newly restored from a coma lasting since birth, and know nothing of this man.

Take a seat boy. Ignorance of his holiness the God-Emperor is intolerable and your education begins now.

Humanity reaches across the stars, our species reigns on thousands of planets of the Galaxy and our ships travel through the hell-realm of the warp by using the AStronomicon to guide the navigators to their destinations. The Emperor, enshrined upon the holy Golden Throne is the source of this beacon, he is the reason that humanity has spread so far and done so much. His mind reaches far and sees further, we know his will through the Emperors Tarot, at first glance a simple card game but upon examination of the cards even the lowest among humanity might know our lord and masters Will. He is the reason we have the astropaths, he hardens their mind by hollowing them out and putting a fraction of his power into them. For this reason they are able to withstand the warp and send messages hurtling across the void, through this method the Imperium communicates with its numerous and distant parts.

But what is the Emperor? He is a man, the best of us and beloved by all. Where you see most psykers are weak and the targets of the the corrupting influence of the warp, the Emperor laughs at such things such is the power of his mind. He united the warring tribes of Terra during the Age of Strife and set out to recover humanitys place in the galaxy, from which we had fallen so far from the pinnacle of the Dark Age of technology. It is said that during the Great Crusade 10 millenia past that it was impossible to look upon him, such was his power. all the average person would see was a shining golden light, at worst they might go blind from the sight of his majesty. Even upon being struck down by his traitorous son Horus at the height of the heresy he did not abandon his people. He sits upon the Golden Throne even now, suffering so that humanity is protected and able to travel the stars; allowing our mighty armies and Fleets to defend our many worlds from the predations of heretics and xenos alike in these darkening times.

This Galaxy is fraught with danger boy, but know this thing when things look the darkest.

The Emperor Protects.
