These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Iron Warriors
Complete Monster: By the end of Storm of Iron, the only thing worse than the Iron Warriors are the Adeptus Mechanicus, who took Hydra Cordatus, once a fertile world, and virus bombed the life out of it to make sure no one else would want it, and have been poisoning Imperial Guard regiments for millennia to make sure no one finds out about the gene-seed stored in the Citadel. Even Captain Eshara, a Space Marine who knows how valuable gene-seed is, was disgusted with how the Mechanicus had acted.
