==Oncolog Hermeticists==

A force supported by the Forgespace in the Tempestus Gap. The Hermeticists are a specialized anti-Nurglite force. Where the NBC suits of the typical PDF or Guard regiment is bulky, restricts field of vision, makes it difficult to breathe, and chafes badly, the Hermeticists' 'iso-armor' makes use of some of the finest technology in the Forgespace to make it suitable for long-term wear. With its padding, lightweight alloy construction, wide-angle visor, fully sealed air supply, internal supply of liquid rations, and catheters, it is intended to be worn for weeks at a time without ever being taken off. Its sealant-resin layers even prevent small armor breaches from compromising the environmental integrity of the armor, and multiple layers of anti-corrosion coating protect the suit from Nurgle's many metallophages. In short, by almost totally isolating the wearer from the outside environment, the iso-armor removes Nurglite force's greatest advantage. It's not completely perfect, but it's the best you'll find short of Astartes. 

In battle, the Hermeticists naturally use a fuckton of incendiary weapons. The flamer:lasgun ratio is higher than any other force in Forgespace, and hand flamers are the most common sidearm. Their doctrine emphasizes unrelenting, OCD thoroughness; no trace of Nurgle's diseases can be left. Massive formations of artillery and bombers saturate target areas with incendiaries and weaponized antibiotics. Then, vast sweeps of infantry and armor comb the ground, hunting down and pursuing any survivors of the initial bombardments. Once an area has been cleared of active enemy resistance (and it never goes as cleanly as the previous couple of sentences make it sound) (Nurgle duh), engineering teams move in for the deep sterilization. Ground-penetrating microwave and UV arrays, super-heavy pyre tracks, millions upon millions of tons of sterilizing agents; once the Hermeticists are through with a region, it is often left entirely lifeless. This is acceptable; life can be re-introduced, but once Nurgle has his grip on a world, he never relinquishes it.

Notably, none of the Oncolog Hermeticists are actually from Oncolog anymore. A reprisal raid by Second Sons forces, in retaliation for daring to set themselves against Nurgle, destroyed Oncolog entirely. However, by then the concept had proven itself; new regiments were raised on a hundred worlds throughout the Gap, collectively taking the name of Oncolog in remembrance.
