<center>'''THE SCION OF EUROPA'''</center>
[[File:Kleisthenes.jpg|160px|right]]
Commander Kleisthenes was one of the oldest surviving Heralds of Hektor when the Heresy began. He had been recruited to the Legion during the first decade of the Great Crusade and was born on one of the human enclaves in the Outer Solar System. Though no record of his precise birthplace survives, by tradition he is considered a child of Europa. In the 41st Millenium, only the vaguest hints on his true story have survived generations of censorship, but a fair representation of his likeness can still be found on medals of "Saint Kleisthenes" worn by pious Imperial Navymen in the Segmentum Solar. For these loyal defenders of the Imperium, the truth of their hero would be too blasphemous to know, but they are permitted to learn a better story about the heroic Master of the fallen Scions of Europa Chapter. Our Order gives all it can.

It is a common misconception among those who have never traveled the void that attacking a solar system involves fighting for each world from the outside in. Even within the relatively small confines of a solar system is space vast almost beyond imagining, too great to be commanded by weapons based on a planetary body. Furthermore, the attacker need not crawl across the plane of the system, instead breaking warp at the poles of the system and moving directly to the inner system. However, when the Traitor Fleet entered Realspace at Sol, the outer system held important secondary objectives. Hektor dispatched Chapters of Space Marines to subdue Loyalist bases that might otherwise have sheltered light fleets operating against Traitor transports.

Most of the Outer System bases were taken without a shot being fired. Alexandri of Rosskar had drafted every human fit for military service in the Solar System and shuttled his conscript armies to key locations - mostly on Terra herself. Those left behind consisted of children, the elderly, and the infirm, and their fates varied according to the whims of the Traitor forces to whom they surrendered. Perhaps surprisingly, the malevolent Black Augurs proved relatively gentle occupiers who had little time for torturing and abusing prisoners. In contrast, Mastodontii forces taking part in this operation quickly abandoned any sense of military efficiency and wallowed in atrocities.

The main Loyalist redoubt in the Outer System was stationed on Europa, an icy moon orbiting Jupiter. Europa's reserves of water had long sustained human life and farms nestled beneath the moon's thick surface ice. Along with civilian stations, a substantial naval base was sustained on the moon, complete with hardened void shielding that would prevent its destruction by orbital bombardment. Loyalist planners deemed Europa the best prospect for a holdout, but few believed the redoubt could long resist a determined assault. For this reason, Alexandri dispatched a mixed force of loyal Space Marines whose gene-sires had followed Hektor into rebellion, believing that if the seed ran true a betrayal would be less damaging on Europa than on Terra. The force was led by Commander Kleisthenes, a Herald of Hektor who had been present on Terra at the outbreak of the war and sworn loyalty to Malcador rather than his own Primarch. Kleisthenes was accompanied by approximately three hundred of his fellow "Wolves of Dawn", seven hundred former Mastodontii, and four hundred marines who had defected from the other Traitor Legions. This brotherhood of lost men fought on beyond even superhuman endurance, grimly holding Europa Station until they were finally overwhelmed by weight of numbers.
