Gras'Vak Conflict

The Gras'Vak Conflict was an Imperial xenocidal purgation campaign fought by detachments of the Jonmarines Space Marine Chapter against the Gras'Vak, a minor xenos species. This conflict was a part of the much larger Reconstruction Wars in the Chapter's history.

History
A race of semi-sentient, bipedal organisms covered in a crystalline exoskeleton known to the Adeptus Mechanicus explorator taskforce dispatched to the world of Grastus as 'Vakirum', the Gras'Vak are one of the first xenos species that the Jonmarines fight during the 'Reconstruction Wars'. Taskforce Terasacariz, led by the Forgemaster himself, comprising of the Eighth Company supported by the Fourth, arrive to aid the explorator team, all the better to, in the Forgemaster's words, "strengthen ties to the Omnissiah". Grastus, a world covered in razor-sharp crystalline structures similar to that which the Gras'Vak are themselves covered in, proves a difficult world to fight upon, but a series of well-placed strikes allows the explorators to recover the ancient technology detected upon the world and evacuate safely. As for the Gras'Vak, the Forgemaster orders the recovery of a wide sample of the remains of slain xenos, alongside a large chunk of Vakirum, all the better to study this unique foe. Information regarding the chemical composition of 'Vakirum' is, however, restricted to all non-Chapter Commandarius persons, as per request of both the Forgemaster and High Librarius Launaas, pending ongoing investigation of it’s constitution.

Captain Advlak, meanwhile, comments on the operation with his usual dry humour, stating that he noticed Forgemaster Terasacariz's 'once-in-a-lifetime' sentimentality, given that the Eighth had assisted the "Black Fourth" all those years ago on Chiralarus, and that the operation on Grastus was a "decent way of returning the favour". The Forgemaster, his agreement belying something of a departure from his usually emotionless state, returns Kodral's humourous observation by stating that "it'd take another Hyvarticus to get another sentimental move like that out of me".
