Following the destruction of the Osroene void power at the Second Kopt Dara, Hektor launched an audacious strike at the Xenos throneworld with a combined force of Space Marines, Mechanicum warships, and [[Rogue Traders (Hektor Heresy)|Rogue Trader]] forces.  Although the speed of Imperial warp travel caught the Osroene off-guard, the defenders quickly concluded that they had suffered another reversal in the Destoona system and concentrated their forces under the guns of War Fortress Tzor.  Hektor led a boarding torpedo assault and his personal prowess not only averted disaster but led to the capture of the great station.  With the Osroene defences unlocked, the Imperial fleet won its final, costly void victory in the Parthorum Xenocide.

Empress Etuili Sevoold responded to defeat in the void by offering surrender.  She first offered to split her domain with Hektor, granting the Primarch all of the stars between Sevoolda and Terra.  When that was rejected, the Empress then pleaded to reign only over her people's homeworld, and finally offered herself as consort to the conqueror if only the Osroene would be permitted to live on as thralls to Terra.  Such pleas were in vain.  Hektor Cincinnatus had not come to the Parthorum Sector to parley with the Xenos, but to destroy them.  Even as Etuili Sevoold begged for peace, the Imperial cohorts were preparing to land on Sevoolda.

It must be said that the Osroene fought heroically in defence of homeworld and legacy, but they had no real answer to the ferocious Space Marines, let alone the god-machines of Legio Tempestus.  The Xenos legions collapsed under the pressure of the Imperial attack.  Erasmos Sergius's warriors dragged Etuili Sevoold from her palace and executed her without trial.  The Imperial commanders were less concerned with the strength of resistance than with the presence of human soldiers among the defenders.  The Great Crusade was a mighty struggle to destroy the dominion of Xenos over the Galaxy and establish man as master - what cause had humans in resisting such a mission?  Hektor's officers did not stay their hands, but many remembered their concerns when the news broke of rebellions in the Parthorum Sector.
