I'm looking to identify the source and artist of the below artwork linked to the Games Workshop Horus Heresy series.

[![death Guard][1]][1]

The image is commonly used to represent the release of a life eater virus by Space Marine Death Guard serfs, and is specifically quoted to be:

*The Death Guard Legion's Captain Ignatius Grulgor's traitorous subordinates suffer a grisly fate after being accidentally exposed to the Life-Eater Virus aboard the frigate Eisenstein during the Istvaan III Atrocity at the start of the Horus Heresy.*

A reverse Google image search identifies the image in three locations:

 - [Warhammer 40k fandom page about Virus Bombs ][2]
 - [Wordpress site about the 5th Horus Heresy Novel Flight of the Eisenstein][3]
 - [Facebook Warhammer 40K Meme group][4]

While not returned in a Google Image search the image is also used on the [Eisenstein][5] fandom wiki page.

As far as I have been able to tell none of these sources directly identify the artist or the source of the work.

The novel [Flight of the Eisenstein][6] is a paperback and does not contain such artwork, and I am not aware of a special edition of this book.

I also feel that the artwork is actually representative of a later story in the novel series, but I cannot at this time remember which one it reminds me of.
