House Manticos - Treachery Consumed: In close vicinity to Adrastapol, the Industrial World of Donatos Primus had fallen to corruption from within, powerful Chaos Cults having called in Heretic Astartes reinforcements to overthrow the local Planetary Governor. With such powerful enemies to fight and no Loyalist Space Marines close enough to respond, the Imperium tasked the Knights of Adrastapol to link up with the surviving Imperial forces on Donatos Primus and reconquer the world in the name of the Emperor. For Alicia Kar Manticos and Gerraint Tan Chimaeros, it became clear that this would be the ideal opportunity to attain their goals: destroy their opponents, reinstall Gerraint as High King and declare Adrastapol's secession from the Imperium. In truth, however, Alicia sought to bring the ancient prophecy of her House to fullfillment.The initial Imperial counterattack met great success, as the forces of High King Tolwyn Tan Draconis and his allies from the Astra Militarum successfully landed on the Penthakhost Peninsula. For Alicia's son, Luk Tan Chimaeros, this was his very first battle and both she and Gerraint faithfully played the part of the proud parents witnessing their son's first battle. The Renegade PDF and Chaos Cultists the Imperial forces encountered in these early stages of the reconquest proved no match for the might of the Imperial Knights now unleashed against them, and the campaign progressed swiftly.Soon, the rebels and their Chaos overlords had been pressed back to the well-defended industrial heartland of Donatos Primus, a heavily fortified region known as the Valle Electrum. As consort to the ruler of House Chimaeros, seasoned advisor and personal friend of the High King, Alicia Kar Manticos was allowed to be present during each and every one of the High King's war councils.On the eve of the Imperium's attack on the Valle Electrum, Alicia Kar Manticos summoned the ancestral daemon to which her House had always prayed, a terrifying entity known only as That Which Dwells In Darkness. Through the daemon, Alicia communed with the true leader of the Donatosian rebels, Varakh'Lorr, a Dark Apostle of the Word Bearers Traitor Legion, and revealed to him every detail of High King Tolwyn's plan and the treachery soon to unfold. As House Draconis and their loyal allies pressed the attack, House Chimaeros and House Wyvorn would allow themselves to fall back and open fire into the Imperial advance.Cunningly planned, the ambush took the Loyalist Knights totally unaware. As the Knights of House Minotos and House Draconis closed with the enemy, House Chimaeros fell back and opened fire at point-blank range. With their Ion Shields still directed to the front, the first shots wreaked havoc amongst the Loyalists, even as House Wyvorn -- tasked with long-range fire-support -- turned on House Pegasson. All three Loyalist Houses suffered severe casualties, including the loss of the Marioness of House Pegasson and the High King himself. Yet the ambush failed to eliminate the treat posed by the Adrastapolian Knights: Tolwyn's son and heir, Danial Tan Draconis, yet lived and was promptly crowned High King to counter Gerraint's claim to the vacant throne. Aimed at annihilating all other Imperial Knights, the ambush was a failure, as the Loyalists still numbered over 50 active Knights, a force to be reckoned with.
