When it became apparent that Hive Fleet Gorgon had managed to create a foothold in the more remote parts of Ferron Proxima there was little the Planetary Defence Force could do by that stage. The alien intelligence had gambled on citing their incursion in some of the desolate wildernesses so as to avoid detection, the gamble being the lack of bio-mass available to fuel their breakout from their planet fall. However, in time the brood nest was able to use hastily formed digestion pits to reclaim what vegetation and local fauna resided in those areas and with this bio-mass were able to evolve their proto-Tervigons into their natural state.

Unfortunately those that did voice such thoughts were soon removed from the populace by the local Inquisition or summarily executed by their PDF Commissars. What did hold true between the two strains was their ability to spawn Termagants. Often they would projectile birth them ahead of their charge, using them as shield, to fearlessly engage the PDF before their brood mother slammed into the preoccupied Ferrons. The only respite the PDF could discern was once again due to their limited stocks of bio-mass as often the beasts spawned would number just a dozen although very occasionally it could be many dozen!

Tervigons were a whole new genus they were rapidly having to come to terms with to draw solutions up for their eradication or at the least containment until the arrival of support from the Adeptus Astartes. It soon became apparent that the creatures had some form of psychic abilities. Initially those skills allowed them to force their progeny to greater feats of endurance or allowing them to control the weaker minded beasts from further distances whilst they stayed in the rear. However at some indeterminate point something changed, whether it be the natural absorption of the Wraithbone shards scattered across the surface of Ferron Proxima or some alien signal that evolved the psychic ability of the creatures following the arrival of the Dark Angel relief force in the battle barge 'Dark Vengeance' no one knows.
[Open in new window]The result though was that suddenly the Tervigons were performing much more varied elements of witchcraft, invariably making them stronger and tougher or giving them the ability to move faster than the eye could see and faster than anything of that size should be in nature. Additionally these skills allowed them to be more aggressive, leading from the front and using further skills to weaken the forces arrayed against the, or making their progeny even more durable in the face of oncoming fire. Regardless it soon became apparent the even the most devastating of creatures the Great Devourer could bring to the battlefields - Trygons and Mawlocs could be pale shadows of what an enraged Tervigon could be - they were seen to tear large tanks apart with ease, smashing Bastions and whole formations apart with their giant crushing claws or scything talons.
[Open in new window]Currently the Tervigons are being kept in check through the efforts of the Dark Angels, disallowing them access to further biomass to increase their numbers. We can only hope the Emperor's Finest will prevail and stamp out their kind.
