Rise of the Dusk Born

The Rise of the Dusk Born is the name of the campaign where the Omni Legion Space Marine Chapter first encountered the Chaos Warband known as the Dusk Born and their Chaos Cultists allies upon the penal world of Lastonoe.

History
An attack upon the penal world of Lastonoe challenged Lucan and the rest of his Formation while aiding an Imperial Guard regiment who also answered the call to aid the planet's forces. Confronted by the Chaos Warband of the Dusk Born and their legions of cultists who freed the prisoners who would attack the forces of the Imperium en masse. Terminators from the 1st Formation and the Warband Astartes were powerful titans of the battlefield that tore through cultists and guards alike as they attempted to slay one-another. Lucan personally fought against Estoden the Unrelenting, while his Honour Guards fought his Terminators. Lucan was faster than Estoden but only because the traitor was slower because of his cumbersome Terminator Armour, Lucan couldn't get close without risking death. For hours the fight continued as the world burned and the situation only got worse with reports of daemonic incursions appearing around the world. Lucan was contacted by Artorias who ordered that he and his men fall back, as they did so the Imperial Guard covered their withdraw, Lucan could hear Estoden laughing and taunting him as the screams of Guards almost made him run back. Lucan never found out the fate of the traitors as he and his brothers left the planet by order of the Chapter Master and could only watch in silence as the Imperial Navy bombed the planet, wiping it clean of all life.
