Diomat
Diomat is a Contemptor Pattern Chaos Dreadnought of the Emperor's Children, currently in use by Fabius Bile's Consortium warband.[1a]
Known to be insane and unhinged, Diomat is kept under strict hibernation lest he run bloody rampages. He was originally one of many such machines used by the 12th Millennial but was the only one of his kind to survive The Shattering. Fabius Bile is sometimes able to use him as an enforcer against rebellious members of the 12th Millennial given his extreme hatred for them.[1a]
During the journey to recover the lost Emperor's Children Gene-Seed on Solemnace, Diomat saved Fabius' life from Palos, a warrior of the treacherous Flavius Alkenex. However in the process his chassis fell off a platform and was damaged beyond recovery. As he died, he reminded Bile to use the gene-seed to save the Legion.[1b]
