The Kaban Project is the seventh short story published in the Horus Heresy that was not originally part of an anthology novel. It was first published as part of the The Horus Heresy: Collected Visions on June 26, 2007 and was later released separately as an e-book. It is also included in the Shadows of Treachery anthology novel. The Kaban Project was republished from the The Horus Heresy: Collected Visions background books as a prequel to the novel Mechanicum.
The Mechanicum priesthood guards its secrets carefully -- few of its technological marvels and processes are fully understood by the Imperium, and many more could be deadly if allowed to fall into the wrong hands. However, in the forges of Lukas Chrom, something sinister has come into being. Rumours abound of forbidden lore and artificial sentience, and a name has been whispered in the dark corners of the Martian data network: Kaban.
