There is a Parade on the planet of Macragge in the Ultramar Sector. After the success of the Indomitus Crusade, the new Primaris Ultramarines parade around, the citizens of the Imperium cheer and roar for them with zeal. The Imperium was on the brink of shattering, collapsing, but after the return of the Primarch Roboute Guilliman from his Millennia long coma, he spent over a decade sorting out the Imperium and fixing logistics. The Son of The Emperor returning to save Man-Kind.
As the citizens of the Imperium cheer, finally they see the flaming sword of The Emperor, and Roboute Guilliman walk through the crowd. His imposing figure, standing tall, even taller than the Primaris Marines. ArchMagos Belisarius Cawl, and Chapter Master of the Ultramarine's Marneus Calgar at his side.
"Citizens of the Imperium! Hear me! Son of The Emperor! The Darkness shall pass, the Imperium shall be reclaimed!"
