"Rage. Despair. Deception. Temptation. Long ago, the Immaterium existed in placid harmony. Then, everything changed when the xenos attacked. Only the Emperor, Master of Mankind, could stop them, but when the galaxy needed him most, he died.

And although his psyker skills are great, he has a lot to learn before he's ready to rule anyone. But I believe the Star Child will save the galaxy."
