The Kaban Machine had been secretly constructed by Master Adept Chrom during the latter years of the Great Crusade. Despite the secrecy involved in its development, whispers of the Kaban Project were heard over the Martian data conduits that whispered the name "Kaban" with some talking about him working on Artificial Intelligence engines on his forge.
Chrom later unleashed the device during an covert attack on the reactors of Adept Maximal in the Gigas Fossae in order to test its capabilities. Once there, it destroyed much of its opposition until it was sighted by a member of the Knights of Taranis. Raf Maven engaged the unit in his Knight where he struggled to combat the machine. After the reactor's explosion, the Kaban Machine seemingly disappeared.
It was later discovered by a cargo hauler by the name of Quixus. Whilst uncovering the device, he was found by Adept Chrom who was accompanied by a group of his Skitarii. After introducing himself, Chrom called the Kaban Machine to him, whereupon it aimed its weapons at Quixus and killed him. Once it was recovered, it became part of the Dark Mechanicum forces that operated on Mars who supported Warmaster Horus during the Horus Heresy and aided the rebel forces at the time of the Schism of Mars.
This machine was different from its peers as it was an Artificial Intelligence. Its bulk was as wide as it was tall and was equipped with a fearsome array of weapons with several being mounted on weapon-tentacles, some of which were recognisable whilst others were a complete mystery. The machines form of locomotion took the form of a heavy tracked unit allowing it to move about its environment. In addition to its armoured skin, it was also equipped with void shielding to protect it from harm.
Measuring ten meters tall, its form was roughly spherical in shape with two arms that were heavily weaponised that were located on opposite sides of one another. There were also high pauldrons that were designed to protect its sensory apparatuses behind which were a number of metallic arms that extended from its shoulders, shaped like massive Mechadendrites that were equipped with a variety of fearsome looking devices.
Heretek Lukas Chrom
Lukas Chrom - Adept Lukas Chrom was the Forge Master of the mightiest forge temple of Mondus Gamma on Mars during the Great Crusade and Horus Heresy eras. He pledged his support for the Warmaster Horus alongside his master, the Fabricator-General Kelbor-Hal. Chrom was quite large, his wide-shouldered frame swathed in a deep crimson robe that did little to disguise the many mechanised enhancements with which he had been blessed. Ribbed pipes and cables looped around his limbs and linked into a hissing power pack that rose like a set of wings at his back. His human face had long since been replaced by an iron mask fashioned in the form of a grinning skull. Wires trailed from the jaw and a pulsing red light filled both eye sockets. Besides his contemporary Urtzi Malevolus, Adept Chrom was considered one of Kelbor-Hal's most trusted followers, a Tech-adept who had followed the Fabricator-General's lead in all things, and who had sworn the strength of his forge city to the Kelbor-Hal's cause.
