The Great Hunt of Fenris

The Great Hunt of Fenris was a small scale conflict involving elements of the 6th,11th, 13th and 18th legions roughly half a decade before the Hive Wars. As the specialist force and expert on worlds that displayed ample hostile conditions, the 13th legion led by the Primarch Cianan Usperian first discovered the world of Fenris, previously hidden from the Imperium in 928.M30 as new stable warp lanes were still being discovered as deep within the Imperium as Segmentum Solar.

Upon surveying the Fenris System and identifying very little in the way of unique resource for the imperial expansion effort, Cianan was fascinated with the unique variations of predators that roamed the world, leading several parties of his legion to the world and capturing several specimens of the fearsome Fenrisian Wolves before once more departing for the ever advancing crusade.

Decades later, reports reached the legions of a monstrous leviathan like creature that terrorised any attempt to bring industrial force to the world. Rising to the challenge, Cianan and a detachment of Nova Bears jumped at the chance to slay a beast of such notable scale and destructive power, a call went out to his brother primarchs to join him on his quest and of them few answered Of the Legions, Odin of the Wild Hunt, Tigerius of the Emperor's Fangs and Elexonen of the Astral Jaguars each answered the call and ventured to fenris with a host of their finest warriors. Upon the surface of the Planet, the sons of Tigerius spent weeks searching the coastlines of the world until they caught sight of the beast. Within hours the legions surrounded and attempted to trap the monster with volleys of boltgun fire while the primarchs did battle with the beast. The Beast was a serpent of titanic scale, capable of swallowing whole a squad of astartes with but a single bite, its very presence drove the seas into fierce storm and its strikes upon the shores and cliffs of fenris shook across the continent.

As The Great Bear took the brunt of their prey with all his might and endurance, Odin and Tigerius tore swathes of flesh with Axe and Claw with Elexonen probing the beast's humoungous form for a weakness. For a day and a night the primarchs fought the beast until the sun dawned upon the second day. Elexonen, Master of Defences buried his spear, a weapon forged deep within the fires of Terra to pierce the skull of the beast. With a mighty roar, the Usperian drove the weapon through the leviathan's skull and into the mountainside where the primarchs smote the carcass of their prey.

Odin left soon after, his search for the kill no longer sated by felling the beast. Of the Primarchs that remained, The Usperian pried a single fang from the mouth of the beast and declared the legion return to baile for a celebration of the triumph. Both Elexonen and Tigerius made the journey with the primarch to engage in the brief celebrations. This event was followed shortly by The Red Feast of Baile.
