My first retcon

A while ago I created a large Dark Mechanicus model named Inquisitor Matthias Balthasar Harnak  . The model I converted was unfortunately broken while I was at work one day and subsequently left in a box in pieces. Unfortunately I could not find all his pieces so I had to reassemble him in new ways. With this new creation and my "new" army I decided to retcon his backstory, which I will keep for another model to be created.

Justinian Lorme was once a techmarine for the XIVth legion, the Death Guard. He was chiefly in charge of maintaining the mechanisms related to containment of the deadly biological weapons of the legion. After the Heresy Lorme's interests began to lead to the forbidden field of warp technology as well augmentic surgery which was usually left to the apothecaries of the legion. Lorme was no longer interested in simple machines and began to combine flesh with technology in disturbing ways. He also began researching the demon engines of the Dark Mechanicum. Now millennia later he has ascended to demonic heights for his contribution to Nurgle's cause. Throughout the millennia of the Long War Lorme has augmented his body beyond that of even the Death Guard plague marines physique. He now towers above those who serve him. His distain for the Poxwalkers often employed by other members of the Death Guard is shown by his chosen form of locomotion. Fit only as fuel for his experiments Poxwalkers find no place among his armies.
