"All of creation suffers, young ones. Only in accepting our own mortality can we make a difference. Only in bearing the burden of our failures can we find the strength to go on. Only in detachment from glory, or honour, or jealousy... from life itself can we hope to spare others from grief. We are Doom Eagles. And we are dead already."
- – Librarian Secundus Thryn
They are extremely grimdark. What, the fact that they're called "Doom Eagles" isn't enough? Their homeworld is dying, and they only choose Gathians who have lost everything of importance to them to become Aspirants.
They use a LOT of Jump Packs and are considered to be some of the best practitioners of the Jump Assault, so just play them on the tabletop with Doom Eagle colors and the assault rules if you want to play a fluffy army. Ironically, or perhaps just as expected for a chapter with such morbid religious beliefs, they proved to be absolutely amazing for fighting Plague Zombies during the 13th Black Crusade, with not a single one falling to the plague. After all, you can't zombify what's already dead. Well, the canon reason was their faith and piousness, but their faith and piousness is centered around a religious belief that they're already dead so the theme still fits.
Those Bloody Magpies "borrowed" a matching power axe and plasma pistol combo off them.
Also not to be confused with the Doom Legion, another Ultramarine chapter with similar name and colors.
The above quote mentions that the Doom Eagles seek to prevent other people from suffering. This automatically makes them one of the few chapters to give a crap about the rest of humanity.
