Night Wyverns

The Night Wyverns are a Black Dragons kill team, split from their home chapter due to their mutations in the Primaris Geneseed. They are officially on record as the first corruption of the Dominus Founding. They display the mutations typical of their predecessors. The Inquisition is want to take offence at the corruption of the geneseed yet this didn't dissuade the Black Dragon Apothecaries from "improving" the Primaris stock.

A Troubled Founding

The Black Dragons, somewhat battered and worn from their involvement in the Third War for Armageddon were in need of new recruits. This should have been no problem were it not for a pending investigation by the Inquisition. Despite many layers of red tape they were granted a small stock of Primaris Geneseed on the one condition that they root out their mutations. They agreed to these terms and within a week the Chapter Apothecaries were scouring every inch of it for weakness and mutation. Despite the "absolute purity" of the stock the apothecaries "didn't perform the checks in time" to root out the mutation, resulting in bony growths in the Primaris Inductees.

When Inquisitor Corvan Grey asked Chief Apothecary about these sudden mutations he was given the response; "Consider that rather than deliberate and malicious breaking of the agreed terms, the Primaris Geneseed is not as pure as was first believed".

This cordial response served to disallow any direct action against the Black Dragons but a deal was struck to send the new Primaris Marines on a penitent crusade. As long as the Black Dragons Primaris marines could function as a military unit for a decade without any extra recruitment, they would be permitted to return to their home chapter.

The Primaris were given new chapter colours, standard armaments and dubbed "The Night Wyvers". They were granted the use of a small dropship to serve as their HQ for the longevity of their crusade and sent out into the eastern fringe of the galaxy.

A Deliberate Accident

The philosophy behind keeping the mutations is that without the impurities of their brothers, the new marines might feel like outsiders from their own chapter. The bone growths have proven to double as excellent melee weapons, ensuring that a marine of the Black Dragons is never truly unarmed.

The Black Dragons eagerly requested new Primaris Geneseed. This aroused suspicion in the puritanical ranks of the Inquisiton due to the seemingly endless investigations that followed the chapter. Though the Inquisitions stance hasn't changed the Black Dragons commitment to the Third war for Armageddon was deemed proof enough of loyalty to the Imperium.

Creatures from Beyond Space

When the newly created Kill Team arrived in the Easter Fringe they were startled by the presence of serpentine warp creatures that appeared out of nowhere and crushed planetoids with their gargantuan bulk. During this time the Primaris Marines were still fresh to the Imperial Creed. The sight of the warp creatures cemented in them a fear that would become a pillar of their philosophy. After acclimating to how and where they appeared the fear turned to a peculiar form of worship.

The mission objectives of the Night Wyverns were mostly isolated outposts on asteroids and prison planetoids run by self-appointed warlords. The Wyverns learnt how to use the arrival the warp creatures, who they called "World Serpents" to strike while the enemy was pre-occupied with the creatures. As such these missions were very time sensitive, resulting in a "strike fast and hard" mentality.
