The Gruefall Crisis. A WH40K Story.

The year is M42. Roboute Guilliman's Indomitus crusade is in full force.

Deep with in Segmentum Pacificus a tide of green flesh painted in deathskulls' blue are stirring, preparing to strike at the fifth most important drydock within the galactic sector. A system the Imperium of Man cannot lose, for the price of a system like this falling into xenos hands are better left to the imagination. Every man, woman and child will fight and work in order to stave of this invasion. While a small group of the Deathwatch Astartes has been sent to aid them. The Orks are not as dim as they seem though, so the fighting will be brutal and the collateral damage high but one thing stands above all.

Gruefall cannot fall.

Also it is my first ever writing project so be kind :).
