Editing Imperial Knight (section)

====Titanicus Vassal Houses====
A few knightly households do not have any degree of independence at all, but are instead subservient to the Titan Legions which they march together into war. These Titanicus Vassal Houses serve as scouts and skirmishers, outflanking and harassing the enemy forces occupying the objectives as well as protecting the Titans from hidden threats.

[[Grimdark|As a result, their knights have a much higher attrition rate than normal]], and their machines are not treated with reverence as with other knightly households. On the other hand, they have access to the most advanced patterns of knights due to the intimidatingly insane battles Titans are guaranteed to participate in.
*'''House Coldshroud''' - House Coldshroud served as vassal to the Legio Gryphonicus, and they drew their pilots from particular families on planets in the Octad, the region surrounding Gryphonne IV. Exactly what became of them after Gryphonne IV got eaten by the 'Nids is unknown, though it's likely they went down fighting on either Gryphonne IV or during the Legio Gryphonicus' last stand on Cadia. Their color scheme is golden yellow and mottled grey with bronze trim.
*'''House Procon Vi''' - House Procon Vi are unique in that they retain a degree of independence, even having their own homeworld, Procon. Many of the Legio Solaria's Princeps and Moderati which they serve under are actually daughters of House Procon Vi, having been given as an offering to the Mechanicum (see Guy Haley's ''Titandeath''); the sons generally become tech-priests while other pilots were these women's descendants. Whether they followed the Legio Solaria's post-Heresy change to allowing men and women to serve is unknown. Their color scheme is black with silver trim.
*'''House Col'Khak''' - Also known as the Col'Khak Collective, House Col'Khak was formed on the frigid Agri-World of Atar-Planitia to serve as vassals for the newly created Forge World of Atar-Median and the Legio Atarus during the Great Crusade. The oldest Scions of the House are said to be little more cerebral matter hooked up to life support systems that look like gilded human statues. At Istvaan V, several Col'Khak Knights were destroyed along with a Demi-legio of Legio Atarus, putting the House on a path of vengeance that saw them deploying independently more often compared to their service during the Great Crusade. Their color scheme is red and black with silver trim.
