As violence erupts from close-quarter battle, Chaos Space Marines and Wrack scream in glee as they are ripped apart! This is the Battle of Belial IV!
Via our good friends at Lexicanum
The renegade Fabius Bile, having studied the Haemonculi’s craft under the Coven of the Thirteen Scars, betrays the trust of his Commorrite mentors. By teaching the secrets he has been entrusted with to the Emperor’s Children in his employ, Bile dilutes the art of the fleshcrafter to an unforgivable degree.
The Thirteen Scars have long watched for just such an infraction. Using energy pillars linked to the Ilmaean suns, they animate their living fortress for war – a towering pillar of flesh fashioned from the bodies of those who have defied them in the past.
The fortress breaches a long-sealed webway node on Belial IV, and lumbers into the Eldar palace that the Emperor’s Children were using as a base of operations. Bile’s heavily mutated Noise Marine allies turn their sonic weaponry upon the hordes of Covenites that pour out from the Tower of Flesh’s yawning maws, rupturing and splitting countless monstrosities as they sally forth. Their charge hits home nonetheless.
The violence that erupts from the close-quarters battle is as intense as it is invigorating, Chaos Space Marine and Wrack alike screaming in glee as they are physically torn apart. The Tower of Flesh itself duels with the corrupted god-machines in Bile’s employ, smashing them aside with its flailing appendages. As their minions fight tooth and nail outside the shattered palace, the Primogenitor Bile is paid a visit in his throne by the Coven lords of the Thirteen Scars.
After the renegade’s private army of horrors experiences a dozen esoteric types of murder at the hands of the Haemonculi, an understanding is reached. Bile’s augmented Emperor’s Children are granted death by masochistic ecstasy, and the Haemonculi depart after surgically ensuring that the renegade cannot speak of his learnings to any other living creature.
