Chaos has united once more.
The quartet of scouts monitoring the systems of 621 confirm this, not with merely picts and feed-capture, but also by the echoes of the Warp the Choirs aboard hear as its ebb turns into a flow of one cohesive whole, the Song of Ruin beating with one heart underneath a cancer of unreality.
Warships fly from moorings with war in heart and battle at their thrum, daemons of Slaanesh and Khorne march as one on the worlds where they fight against humans holding desperately for centuries against onslaughts eternal. At the same time, banners of Rot and Sorcery are raised high, joined by screaming standards moaning under pleasures beyond the souls of the sane, their vessels gathering unto the worlds that belonged once to them but are now being cleansed by the Mashan.
And above them all sits the Chaos Lord Ssli'sazarl, a name shouted again and again within intercepted communications and foul prayers cast into the Warp, a Xenos of unknown origin triumphing above every Champion sent against them, commanding legions of cultists with the same hands as they order the construction of ships and the raising of armies from the dead and living alike.
Far darker news comes for the innocents choked by Chaos' Yoke of Holy Herastis and Holy Herastus, dozens of fat-bellied ships entering their atmospheres with empty holds and slavering maws, leaving with bursting cages and wailing souls, their destinations deeper within the Sub-Sector and then further onto planets or staying within the ships outright yet sent against the fronts Terraward and Anti-Terraward alike.
And it is with the cold rage of those beyond wrath that our analysts watch as a Chaos Fleet sludges into Lethysan...and sets up defenses. It is not a base for an offensive, nor a set of warehouses to support logistics, but static defense stations, minefields, hardened bunkers on moons and asteroids, and small shipyards likely intended for maintenance and repair.
All the while, they continue to commit atrocities beyond counting as they gear up against their two oldest foes in 621.
Even the report by the Celestial Choir, tinged with saddened pride as it is that their available numbers have grown so much that they feel confident in pursuing directed research into Melodies does little to stem the tide of plans crafted to invade, conquer, and liberate those who suffer for no other reason than pure malice. Yet the reports that the Choirs have managed to decipher a way to divine the Unstable Warp Routes of the galaxy certainly does put a pause in those.
