Blue Sentinels

"*Bound by an unbreakable oath, We have sworn to defend the Imperium to the death. Those who dare attempt to seize our worlds, will be pacified by steel. We deliver swift and uncompromised justice. We are the Sentinels of Blackrock. We are the Angels of Death, and we shall know no fear!*"
—Chapter Master Corus Targray

## Blue Sentinels

### Warcry

"Sentinels of the Imperium! Death to it's foes!"

### Colours

Dark Grey and Yale Blue

The **Blue Sentinels** is a Loyalist Codex Astartes-compliant Chapter of Space Marines created during the 5th Founding in the late 33rd Millennium from an unknown origin. The Blue Sentinels under **Chapter Master Corus Targray** was created for their precision and care of the Imperium's people, utilizing their small, maneuverable forces in engagements.

Created during the "Mending" also known as the 5th Founding, the Blue Sentinels was one of the eight chapters whose mission was to mend the scars of civil war and unrest within the Imperium. The Blue Sentinels frequently operated on their own and were far from the support of other Imperial Forces. This situation is often cited as the main reason for why imperial administration is light and people have far more "freedom." However, this also means that the Chapter's Homeworld is more lightly defended. This forces the local to rely more on themselves, should things go amiss, making them hardy and capable individuals.

## Chapter Gene-Seed

It is unknown, which gene-seed was used during the Founding of the Blue Sentinels. Some sources have since hinted that they utilized the Salamander's gene-seed. This would be unusual because Vulkan's gene-seed suffers from the mutation known as the Salamanders' Melanochrome gene-seed organ, making the Salamanders' gene stock to be rarely utilised by the Adeptus Mechanicus for new Foundings.

## Chapter Combat Doctrine

"*We are the guardians of our people. We stand strong against all invaders. Duty is our shield, order: our weapon. When we defend the weak, we are...immortal.*"
—Captain Dorian
## Chapter Beliefs

The **Promethean Cult** is a variation of the faith of the standard Imperial Cult that influences the Blue Sentinels Chapter. The Astartes of the Blue Sentinels Chapter believe deeply in the virtues of self-reliance and self-sacrifice for others.

## Prayers and Oaths

What is Emperor's Will? That we fight and die.
What is Death? It is our duty.
What is your Duty? ...

Where there is doubt, I shall sow faith
Where there is shame, I shall point atonement
Where there is rage, I shall show its course
My word in the soul shall be as my bolter in the field.

## Notable Blue Sentinels

* Chapter Master Targray - Corus Targray was the first Chapter Master of the Blue Sentinels.

## Chapter Appearances

#### Physical Appearance

The Blue Sentinels are suspected to be a Successor Chapter of the Salamanders due to their similar physiques. It is unclear whether they have the same tendency to develop ebony skin, which is due to the mutation in the DNA of the Salamanders' Melanochrome gene-seed organ.
