Battle of Sanus

The Battle of Sanus is one of the earlier recorded raids conducted by the formed Crow's Children Chaos Warband, which had fallen to the corrupting influence of the Ruinous Powers over two centuries earlier. This warband's insatiable lust for death would them throughout their former home system and eventually earn them the moniker, 'The Scourge of Asteria'.

History
Following years spent in the Warp with their new Daemonic masters, the Crow's Children reappeared in the Aegimius System, and immediately set to laying waste to the Civilised World of Sanus and its young Imperial settlements. Descending upon the helpless populace with their Corvian-styled jump-packs, the Children massacred all they could see, reducing cities to rubble in a matter of hours with their Warp-forged weaponry. The Penitent Knights, however, rushed to annihilate the traitors with all speed, but alas arrived days too late to save the civilians of Sanus due to the Children virtually destroying all communication from the planet. When the Knights arrived on planet, they were greeted with a sea of bones and broken buildings. But in Thadeliv, Sanus' capital, the Crow's Children erected grand effigies of the Chaos Gods from the metal and bone reaped from the innocents of Sanus. A fierce battled followed as the loyal and traitor marines engaged within the confines of Thadeliv, with great costs to both sides. Lithandros and Daedelus dueled in the throne room of the previous Planetary Governor, while the rest of the Knights fought in an almost berserk state against their traitor brothers, for both their betrayal and the devastation they had caused. Ultimately, Daedelus had eventually tired out the Highlord to the point where he was able to knock Lithandros to the ground and rip off the loyalist's left arm from his body with his power fist before himself being wounded by bolter fire from Knight Captain Balder Karn, of the Order of the Gryphon. Subsequently, the Crow's Children retreated back into the Warp using a portal they had crafted.

After the idols of the Chaos Gods had been utterly destroyed by the Penitent Knights, Lithandros deemed that the barren world of Sanus would become the Cemetery World of Penance, an eternal reminder of the consequence of their failure to defend the innocent from the wicked jaws of the Children.
