Imperial Knight Heraldry - House Heraldry: The Knight houses trace their origins to a period thousands of standard years before the birth of the Imperium of Man, so their banners present a visual language that appears to have evolved through time. Each began as a simple device, such as the white horse of House Terryn. Over the millennia, new alliances and significant events caused it to evolve into something grander, reflecting the complex relationship between the Knight house and the Imperium itself.For instance, the Terryn white horse is symbolically linked to a vision that the house founder had way back in its distant past. Over the millennia, more heraldry, such as the helm above the crest and the swords behind were added (symbolic of an ancient battle), as was the house name.Later, when High King Seuitonius Terryn swore allegiance to the Imperium of Man, the crest was marshalled, with the half-Aquila falling on the right side, and resplendent eagle wings as supporters. This half-and-half icon shows the observer the relationship between the knightly house and the Imperium, and the dichotomy of the Terryn Knights' loyalty to their house and the wider Imperium.Other forms of Knight house heraldry, such as the house banner of House Griffith, possess subtle nods to events in their long, glorious history in the crest and secondary devices they employ. These are often very grand, with a mythological aspect to whatever symbols are chosen. House Griffith has fought wars against large reptilian creatures named "dragons" during their ancient history, and as such wear dragons as their crest. This desperate struggle served to harden the Griffith Nobles into skilled and fierce warriors.Millennia later, House Griffith is sworn to the Imperium as a member of the Questor Imperialis, and has earned a reputation for producing some of the most formidable warriors ever to sit upon the Throne Mechanicum. The heraldry of House Griffith is halved with a dragon motif, connecting to their ancient history, and a red-winged Aquila, professing loyalty to Terra. What truth lies behind the dragon symbol is now the subject of legend as much as historical fact, but to the warriors of House Griffith, it is very important.Essentially the same is true of the Questor Mechanicus houses. Their imagery tends more towards the industrial, with harder edges to their designs, where tools replace the swords and axes displayed by other houses. In the place of Imperial Aquilas, these Imperial Knights wear the half-cog of the Adeptus Mechanicus. The same dual-split remains here, with the Knights' loyalty divided between the house and the Cult Mechanicus.A perfect example is the crest of House Raven, foremost among the knightly houses aligned to the Adeptus Mechanicus. Their ancient alliance was brought about when a lord of House Raven witnessed the Magi of Forge World Metalica rouse to life Knight suits that had lain inoperable for centuries. The seat of House Raven's power is their indomitable fortress known as the Keep Inviolate, a foreboding structure on the Knight World of Kolossi. The full house crest of Raven bears homage to their heritage with the dual image of the Keep Inviolate and the Mechanicus' Opus Machina.Finally, each Imperial Knight has the right to wear his or her own personal heraldry. Those of Questor Imperialis houses wear this on the front-right shoulder plate of their Knight. The form it takes is a matter of personal choice, although different houses have their own traditions. Questor Mechanicus houses do not typically bother with this at all. The Nobles from houses such as Krast and Raven are willingly subsumed into the service of the Machine God, and do not fear for their independence.
