Editing Savage Hearts (section)

===Notable Campaigns===

During the Second Vetrovnak Incursion, Dov-Kelor was one of the planets close to the Vetrovnak's first spearheads, and the Savage Hearts found themselves fighting a desperate battle against terrible foes. The ever-hungry Vetrovnak looked upon Dov-Kelor's colossal Hive Cities and the billions of prey animals within, and deemed it a priority target for conquest. What they did not know was that some of the Emperor's most vicious children also called Dov-Kelor home, and they did not take kindly to the Vetrovnak's presence. Fortunate indeed were the people of Dov-Kelor as the Vetrovnak entered their system, for the majority of the Savage Hearts Chapter was on-planet, rearming after an extended campaign chasing a cabal of Black Augurs across half the Segmentum, a duel which required nearly the whole Chapter's might in order to pin down their elusive, Warp-blessed prey. Eight hundred and sixty-three Astartes looked to the sky as blasphemous vessels began to descend, and grimly readied themselves for war. 

Shaking off the coat of dirt and plant life which had grown atop the Chapter's slumbering voidships, the Savage Hearts raked the Vetrovnak with unrelenting firepower, knocking many of them from the sky before ever feeling soil. Yet still the Vetrovnak came, now maddened with rage as well as blood-hunger. Though the Dov-Kelor military forces and the Savage Hearts fought like men possessed, they could not halt the tide forever, and a great wailing arose from the Hive Cities as breach after breach let the harvesters enter, doing as they pleased. After three months of nonstop carnage, the remaining Savage Hearts came to a momentous conclusion; there was indeed something they hated even more than the forcees of Chaos, and it was even now glutting itself on their people. 

Quietly, quietly, the Savage Hearts withdrew from the field, and an eerie hush fell on Dov-Kelor. The Vetrovnak retrieved many an Astartes body, some even slain by Astartes weapons, and contentedly concluded that the Chapter was no more, that their will had left them and terror took them whole. Yet deep below every Hive Spire, shapes moved through the darkness, crawling through abyssal sewage pipes and drainage tanks with aid of neither sorcery or technology, squirming through collapsed passages and vile gatherings of filth with dire purpose and utmost secrecy. Their minds sealed and sparks dimmed to such an extent that even the best psyker would have had difficulties telling man from beast, the Savage Hearts made their move. And had the Vetrovnak looked a little more closely, or been a little more familiar with Astartes bodies, they might have seen that what they assumed to be friendly fire was instead mercy kills for the dying wounded, enacted with all proper ritual that the warrior might know victory even after death. A mighty ruse. 

At dawn on the ninety-seventh day of Vetrovnak incursion, fifteen Hive Spires burned in thermonuclear pyres as their fusion cores detonated from within. 

The Vetrovnak reeled in shock, watching from orbit as untold numbers of their own kind vanished into a death from which no nanomachine could save them. They had underestimated the Savage Hearts' commitment to victory at any cost, and paid a terrible price. Though Dov-Kelor and the Chapter were nigh-annhilated, reports from the surface were already arriving, telling the tale of human forces emerging from pits, trenches and tunnels criscrossing the boglands and shattered mountain spires, scything down any Vetrovnak who yet lived after the flame's passage. A retreat was called, one of the few such actions during the Second Incursion. It would be more than three millennia before Dov-Kelor stood proud and strong once more, yet victory was theirs despite the cost. 

However, it can be said that the Savage Hearts' vengeful defense of their homeworld may have even done more harm than good in the end. More than one Imperial Scholar has surmised that without this terrible lesson proving the Imperium to be a real threat when cornered, the Vetrovnak might have been less murderous, less destructive, and more willing to ultimately withdraw from Imperiual space than they in fact proved to be. Having come face to face with Humanity's champions, the Vetrovnak did not soon forget Dov-Kelor.
