Emperors Fangs

The Emperors Fangs are one of the First Founding Chapters of Space Marines created at the onset of the Emperor's Great Crusade. Originally known as the Death Hounds, during the later parts of the Great Crusade, the then 11th Legion was lead by their Primarch Tigerius Ferrox.

The 11th Legion were known for their position as the Emperors Executioners. The only Space Marine Legion to be trained to specifically combat other Legiones Astartes. Due to this, they were often sent to pacify other legions if their actions got out of hand.

Origins
The 11th Legion of Adeptus Astartes was originally deployed on 784.M30 as part of the 3rd wave of Adeptus Astartes deployments. Upon their creation, the 11th Legion were sent to the openly hostile Technobarbarian state, Sa’afrik. The 11th were to be assisted in this endeavor by the Caperin Dustrunners, an Imperial Army regiment currently fighting in Sa’afrik. Upon joining the fight against the Technobarbarians, the 11th devised an effective strategy of neutralising hostile leaders first so that the lesser soldiers would scatter, only to be chased down and slaughtered by the 11th. Due to this particular strategy, the men of the Dustrunners began to refer to the 11th as ‘Death Hounds’, a name which inevitably stuck. During this campaign, the inherent brutality of the 11th began to show, as they slaughtered all they could, showing no mercy to the barbarians until they finally surrendered or all the combat-ready individuals were dead.

Legion Gene-seed
The geneseed of the Emperors Fangs is somewhat stable. During the transplant process, the geneseed greatly favours male recipients and thus, extremely low amounts of female aspirants survive the transplants. All of the standard geneseed organs work as they are expected to, however, the progenoid glands of the Emperors Fangs produce an extra geneseed organ, known as the Viscera Gland. This organ seems to be responsible for the lack of surviving female aspirants.

The Viscera Gland

The Viscera Gland is implanted in the brain, attached to the Pituitary Glands. This organ, when the body is in high-stress situations, such as combat, will release a chemical cocktail of various chemicals and hormones that will cause the Astartes to have incredibly increased energy and physical output. Under normal circumstances, all this will does is increase the combat effectiveness of the Astartes, however, in exceptional circumstances, the geneseed will go into a period of excessive production. This results in the Astartes turning into a mindless berserker, attacking all that is near it in an unrelenting rage. Normally, this will go on for a short amount of time, and then the Astartes will be fine. But, if this happens frequently, it will result in permanent brain damage for the Astartes in question. Also, if the period of excessive production occurs for a large amount of time, it will result in complete organ failure, killing the Astartes.
