Erranigos Vindicta Cohort

"The might of the Adeptus Mechanicus is upon you, surrender yourselves for questioning and summery execution."

- Erranigos Vindicta Cohort standard pre-battle announcement.

Comprised of the scattered remains of various cohorts most of which being cohorts which had divided against each-other in the face of the Mechanicus civil war and Fabricator-General Kelbor-Hal's joining Horus against the Emperor. The Erranigos Vindicata Cohort was swiftly brought together with the intention of the Adeptus Mechanicus of having them swearing to join the loyalist forces in tracking down and slaughtering the remaining traitors. However the Cohort was forged and battle ready nearly too late to join the loyalists in their pursuit of the heretics and the vows of the Myrmidons were changed to the elimination of any and all heretical forces.
