Anyone interested in helping me extend on a narrative?

I am working on getting my wife into Warhammer, we are starting with some kill team action. She has started to show some interest in the Orks. Since Orks are scavengers, their uniforms reflect the scores of fallen Krieg, repurposed for their conquest. I found this snippet online and thought it was a great starting point. She’s a big book person, so without a decent narrative, she’ll never get into it.

Thanks in advance for the help!

“ Krieg, the Imperium's most infamous and bleakest war world, found itself under attack after the birth of the Great Rift. The initial waves of traitors were dispatched with contemptuous ease. It would not be so for what came next. Waaaagh! Ironskull descended on Krieg, the immense Ork invasion bringing with it a spearhead of six million Blood Axe Orks. Shells ceaselessly fall night and day as Orks and the DeathKorps clash on a planet-wide tank and trench warfare.”
