Medusa V - Turmoil: Even as the Imperial forces in the region attempted to come to terms with the onrushing tide of destruction from the Warp and plan the evacuation of Medusa V, more sinister events were unfolding. The T'au Water Caste arrived on the world, seeking to carry on diplomatic negotiations as they sought to lay claim to the world, desiring to use it as a base from which to penetrate the secrets of the Warp.Unrest boiled on the surface of the planet, mirroring the hideous Warp Storm that was approaching it. Several of the cities that contained the descendants of the refugees from Medusa IV openly revolted agaisnt the world's Imperial authorities.Imperial planetary governor Lord Soloman, the world's ruler, hoped that this was only a reaction to the dire threat approaching his planet, but with every passing solar day news of the rebellion grew worse.The attendant tech-priests of the Mechanicus who operated the vast auspex arrays in the orbital space docks above the planet, detected a series of astronomical energy spikes. The first had originated on Medusa VII, a blasted and lifeless planet that had previously been dismissed as completely unremarkable by the Imperium.A second and third new energy signature was then detected on Medusa V itself, one in the uninhabited southern region of the planet and the other on the outskirts of Macavius Hive, the second largest population centre on the world.Rumours soon abounded that alien invaders were laying siege to the city, alien invaders who matched the description of the feared Necrons, indicating that perhaps Medusa VII had been one of their Tomb Worlds.Awakened from their long hibernation by the proximity of the Warp Storm, the Necrons had sought out the closest populated world to begin one of their genocidal "red harvests" of all the intelligent life they could find that they believed was squatting on territory that belonged solely to them.Three vessels, part of an Explorator fleet heading further into the Eastern Fringes, were then attacked under mysterious circumstances, within surveyor range of Medusa V's Imperial Navy picket fleet. Several frigates were despatched to assist, but the Imperial warships arrived to find the vessels were nothing more than drifting hulks, all crew and passengers lost with no sign of the attackers, though the Drukhari were suspected, and believed to be moving deeper into the Medusa System in search of more slaves to feed their eternal hunger.As if matters were not bad enough, more than a hundred farming colonies on the northern edge of Medusa V's settled continent were destroyed in a spate of barbaric attacks by an Ork WAAAGH! that had been drawn to the Mining World by the growing conflicts being fought on its surface.All the farming machinery was looted and not even the great reaping machines were left behind by the attackers as only smouldering ruins and scattered corpses of the farmers remained.In reaction to these attacks, the remaining farmers began to abandon their settlements for fear of similar assaults. Every day more agri-labourers abandoned their communities and the threat of famine on a global scale for the people of Medusa V became more of a reality.Deathwatch Space Marines of the Inquisition's Ordo Xenos, tasked with eliminating the remaining splinters of the Tyranid Hive Fleet Kraken, warned that a sizeable surviving portion of that hive fleet had broken its course following a titanic engagement with the Imperial Navy at Lycanis.Librarian Andreas of the Deathwatch postulated that the vastly swollen Rapidity might be acting as a psychic beacon to the Hive Mind of the Tyranids, drawing the vile creatures towards it.The best efforts of the Ordo Xenos to turn the Tyranids aside amounted to nought, and a full-scale invasion of those rapacious aliens soon added to the utter insanity that was reigning on Medusa V as the world approached its own apocalypse.
