Codex Dark Angels
Never forget, never forgive! The Dark Angels make war with stoic, merciless determination. Marching ever forward, disregarding the attacks of their foes, they gun down their enemies with grim efficiency, never once displaying any sign of weakness or pride. Wrapping themselves tightly in the archaic rituals of battle, they seem almost desperate to distance themselves from those they seek to protect - indeed, lurking behind their courage and heroism is a secret stain upon their honour that, if revealed, would destroy everything they have struggled to bring to bear.
No matter the foe, regardless of the odds, the proud warriors of the Dark Angels stubbornly refuse to accept defeat. Descendants of the First Legion, they stand foremost amongst the Chapters of the Space Marines, Mankind's mightiest defenders. None fight with more grim determination than the Dark Angels, and their renowned special companies - the Deathwing and the Ravenwing - are held in awe by allies and enemies alike.
From their destroyed homeworld of Caliban, the Dark Angels go to war. One of the original founding Space Marine Chapters, the Dark Angels have served the Emperor since the very formation of the Adeptus Astartes, and have fought through countless campaigns in his name. Their chapter is now based out of The Rock - a huge asteroid which has been equipped with Warp Engines, and is home to the much-feared Interrogator Chaplains who use their unique skills to find out the answers about the Fallen.
