Lysimachus Cestus - A Deadly Warning: The Vangelis spaceport was a vast orbital station built into a large moon and based around several hexagonal blisters into which docks, communion temples and muster halls were housed. The bustling spaceport was crammed with traders, naval crewmen and mechwrights. A large proportion of its area had been given over to the Astartes of the Legions. Vangelis was a galactic waymarker and small numbers of Astartes involved in more discreet missions used it as a gathering point. Once their objective was completed, they would congregate at one of the many muster halls designated for their specific Legion and await pick-up by their warships or other transports. Though little more than a company from any given Legion would be expecting transit at any one time, Sectors Kappa through Theta of the spaceport were at the complete disposal of the Legions. Few non-Astartes were ever seen there, barring ubiquitous Legion Serfs and attendants, though occasionally Remembrancers would be granted brief access in concordance with the Emperor's directive that the Astartes were to maintain good relations with the human populace.Ultramarines Captain Lysimachus Cestus and nine of his Battle-Brothers had been on Vangelis for over a month. They had been acting as an honour guard for an Imperial dignitary at nearby Ithilrium and were consequently separated from the rest of their Legion. Their sabbatical had passed slowly for Cestus. The fact that The Fist of Macragge was in transit to extract them from Vangelis and ferry him and his brothers to Ultramar and their Primarch Roboute Guilliman and Legion filled Cestus with relief. He longed to embark on the Great Crusade again, to be out on the battlefields of a heathen galaxy, bringing order and solidity. Word had reached them that the Warmaster Horus had already departed for the planet of Istvaan III to quell a rebellion in that star system against the Imperium. Cestus was envious of his Legion brothers, the Death Guard, Emperor's Children and World Eaters who were en route with the Warmaster.But Cestus would not be reuniting with his Legion. He soon learned of the destruction of The Fist of Macragge through an astropathic psychic death-scream received by the station's Astropaths as well as experiencing, what he believed to be a vision of Macragge. Cestus gathered the nine Battle-Brothers under his command and also acquired additional Astartes support from the Wolf Guard Brynngar Sturmdreng and his Space Wolves and Captain Skraal and his World Eaters, who also happened to be in transition at the Vangelis spaceport. Skraal led 20 World Eaters on the Wrathful and Cestus was determined to make the best use of them. Brynngar had brought the same number of Space Wolf Blood Claws, and while they were raucous and pugnacious, especially when forced into idleness in the confines of the spaceport, they did not harbour the same homicidal bent as the bloody sons of Angron. With 50 Astartes and the vessels of their makeshift fleet at his command, Cestus hoped it would be enough for whatever lay in store.Captain Cestus also took the initiative and assembled a formidable interdiction fleet from the resources available at Vangelis spaceport and quickly departed in search of any trace of The Fist of Macragge or its killer. Necessity had forced Cestus's hand, and whether he liked it or not, this is what he had been dealt. As Fleet Commander of the Ultramarines 7th Chapter, Cestus was able to use his credentials to requisition elements of the nearby Saturnine Fleet under the command of Rear Admiral Kaminska, which included the Imperial warships Boundless, Fearless, Ferocious, Ferox, Fireblade and Wrathful. Cestus was also soon contacted by a Thousand Sons' vessel called Waning Moon, commanded by Fleet Captain Mhotep, who also wished to volunteer his services, though he had no squads of Thousand Sons Legionaries, just cohorts of naval armsmen at his command.
