Cleansing of the ''Death of Integrity''

The Cleansing of the Death of Integrity was a space hulk purgation campaign carried out by a combined forces comprised of elite Terminator-armoured Veteran Companies from the Ebon Knights, Blood Drinkers and Novamarines Chapters, to cleanse and the notorious space hulk known as the Death of Integrity. Despite the severe loss of life, the sacrifice of the Astartes wasn't all for naught, as they were able to recover a remarkably well-preserved Standard Template Construct database in the process.

History
In 887.M39, the Space Hulk, codified Death of Integrity was seen near the world of Vol Secundus. The ancient ruin had been encountered twice before in recent centuries, each time preceding the appearance of Tyranid forces upon nearby worlds. A general call for immediate Adeptus Astartes assistance was issued, with members of the 1st Companies of the Ebon Knights, Novamarines, and the Blood Drinkers Chapters responding to the call for assistance. Exhibiting a tremendous amount of co-operation, the three Chapters deployed nearly 200 Space Marines equipped with Terminator Armour to the massive Hulk.

Over the course of two months, the combined forces thoroughly purged the Space Hulk of a rampant genestealer infestation. All three Chapters suffered terrible losses, as the xenos were well-suited for battle within the cramped and toxic environment. Though the battle was costly in terms of damage to armour and loss of life, the ultimate prize was stunning. Hidden deep within the hulk's ruins was a remarkably well preserved Standard Template Construct (STC) database containing information on countless lost technologies. The Adeptus Mechanicus gladly accepted this priceless artefact and went so far as to repay each Chapter with a newly commissioned Strike Cruiser.
