The humans worshiped the Herald of Nurgle as a god and he left nothing but death and decay in return. In time Typhus left, his work finished. Before leaving he left a fragment of his armour filled with his dark power, in a temple the people of Maypax had built for him. Soon after the planet was wracked by Warp storms that left it isolated for five hundred years. When the warp storms ended the Imperium came to the planet, in search of the fragment of armour, but so had the Orks.
