House Col'Khak, known also as the Suzerain House of Col'Khak or The Col'Khak Collective, is an alliance of Imperial Knight Households that were founded in the latter 30th Millennium during the Great Crusade on the frigid Agri-World of Atar-Planitia in support of the then recently implanted Forge World of Atar-Median. As such, the Collective owes its fealty first to the Mechanicum -- through its bonded Forge World of Atar-Median -- and second to the Imperium.
Since its inception in the early years of the Great Crusade, the Col'Khak Collective has followed the strictures of the Sidon Protocols, effectively bonding it to the Atar-Median Forge. The warriors of Col'Khak have trained to function flawlessly alongside the Atar-Median Taghmata and the Titans of the Legio Atarus ("Firebrands"), and have benefitted from the continuous supply of Magaera and Styrix pattern Knight armours from the forges of Atar-Median. Though many conservative knightly Households consider the Styrix to be a dark and malevolent pattern of armour, amongst the Mechanicus-oathed House Col'Khak, the Styrix is held in higher esteem, especially among those scions who have undergone extensive augmentation in honour of their enigmatic patrons and share their antipathy for the weakness of flesh. The pitiless thrall-Knights of House Col'Khak are renowned for fielding entire formations of these machines in support of the Legio Atarus, sweeping clear enemy infantry from the Titan's feet in a furious blast of energy beams and cleansing radiation. Such is the level of integration between the House and its Mechanicum allies that the Archmagos Prelate, or lead Princeps of a battlegroup to which the warriors of Col'Khak are assigned, is treated with some veneration and granted full authority over the assembled Knights. Indeed, the warriors of Col'Khak have long since adapted many of the rites and practices of the Cult Mechanicus for their own use, treating all technological artefacts as precious relics and heirlooms of the Collective. Many even voluntarily accept extensive levels of augmentation, although aesthetically choose to remain human in overall appearance. It is said that many of the oldest scions of Col'Khak are little more than preserved cerebral matter and life support systems. Outside their Knight armour, they appear as almost animate statuary to some in the most extreme cases, their gilded and argent plated bodies matching an ideal of human form. After the Dropsite Massacre on Istvaan V, and the sacrifice of a full demi-Legion of the Legio Atarus and their supporting Knights, the warriors of Col'Khak clamoured for assignment to mustering maniples of Titans, eager to seek revenge for their brethren slain in the opening moves of Horus' rebellion.
- Drop Site Massacre of Istvaan V (566.006.M31) - The Col'Khak Collective dispatched a full supporting cadre of Knights in assistance to a Legio Atarus demi-Legio sent to support the Loyalist assault on Istvaan V. All were subsequently lost alongside the Titans of the Red Naga War Maniple. The warriors of Col'Khak swore revenge on the Traitors and were most eager to join the battle against the Traitor forces of Warmaster Horus.
The military strength of the Col'Khak Collective is currently unknown, though it is believed to conform widely to a Questoris-type Household. The Col'Khak are known to be extensively equipped with both the Magaera and the Styrix Pattern Questoris Armour, both manufactured continuously on Atar-Median, which leads to the conclusion that the Col'Khak Collective is regularly used as anti-infantry support for the Legio Atarus.
The colours of House Col'Khak are not listed in current Imperial records. But due to their close association with the Adeptus Mechanicus, one can assumed that they have more than likely adopted the signature red colour of the Maritan priesthood of Mars.
House Col'Khak's coat of arms is not listed in current Imperial records.
