The Shattering

The Shattering is one of the most lamentable events in the history of the Shattered Star Space Marine, when the Chapter lost half their battle-brothers when their Chapter fleet was caught in a furious warp storm while enroute to relieve a beleaguered Imperial world that was under siege by an Ork invasion. Enraged at the loss of so many of their fellow battle-brothers, the Chapter unleashed their pent up rage against the unsuspecting greenskins, slaughtering them in the most horrific ways imaginable.

History
This event is a stain on the chapter as that event cause the loss of half of the chapter. While enroute to answer a distress signal, the chapter entered the warp while a warp storm emerged. This caused half of the fleet to be lost in the warp. When they reached their destination the chapter fell into a deep rage, wanting someway to cope with the fact that they lost over 500 battle-brothers in a blink of an eye. The locals were shocked at how brutal the greenskin invaders were butchered, as the battle-brothers were so fierce that some Orkz even ran for their own survival. Something that is unheard of for Orkz.
