As Company Master Jevriel of the Dark Angels made landfall, his men were quickly beset by a swarm of Tyranid, preventing full-scale deployment. The markings on the brood indicate Hive Fleet Behemoth, the largest Tyranid invasion force previously believed defeated. Whether this is a lost splinter fleet, a resurgence or holdout of the original force, or an entirely new hive fleet is unknown.
While Jevriel advanced through Tau ruins, his flanks were attacked by monstrous creatures. To the right, a whirlwind tank and heavy weapons team were crushed by a charging Carnifex, who suffered severe wounds but limped on like an unshakable nightmare. Worse still, an immense Hive Tyrant Queen swooped down from the skies, slicing through an entire squad of marines in seconds. With the primary force surrounded and further Tyranids infesting the ruins and local flora, perhaps only the arrival of the powerful psyker Librarian Cheriel and a unit of Deathwing Terminators bought the Angels of Death enough time. Forced to move back, the Dark Angels were nonetheless able to establish a ground presence on Kau’Rela. However, the immense carnifex and ferocious Tyranid Queen now had a taste for Dark Angels and lurk somewhere in the dust clouds of the moon.
Unnoticed by both, a set of Tau drones records the battle and relays the information back to the Tau interdiction fleet hiding off the dark side of the moon.
