Changes

Unlike the Questor Imperialis, which worship the [[Imperial Cult]], those of the Questor Mechanicus venerate the [[Cult Mechanicus]] and the [[Omnissiah]]. Its members have the unmistakable influence of the Adeptus Mechanicus on their culture, and their Knight Worlds are often more industrial and urbanized compared to those of the Questor Imperialis.{{Fn|29}}

The Nobles of the Questor Mechanicus are broadly similar to those of their [[Adeptus Terra]] counterparts. However instead of titles such as High King or Baron, these Nobles utilize Adeptus Mechanicus terms such as [[Princeps (Knights)|Princep]]s and in turn command lesser vassals, bondsmen, and serfs. These rulers are pledged to a greater [[Forge World]], taking part in their defense in exchange for technology and resources, making Questor Mechanicus Houses particularly well-supplied. Besides these roles, their Nobles often take part in [[Explorator Fleet]]s, [[Archaeotech]] crusades, or the protection of Mechanicum trade routes. Their courts will consist of [[Tech-Priest]]s, who ensure the House's [[Sacristan]]s are more powerful and influential than those of the Questor Imperialis.{{Fn|29}}

The Houses of the Questor Mechanicus are usually less autonomous than those of the Questor Imperialis and unlike with Houses sworn to the Adeptus Terra, Mechanicum-sworn Houses may be stationed with a [[Titan Legion]] permanently, where they act as vanguards, flanking support, and engagers of lesser foes.{{Fn|7d}}{{Fn|29}} However Knightly Princeps are still driven by honour, their Nobles are rarely slaved to the will of their sworn Forge World's Tech-Priests. Sometimes this puts their nobles at odds with Tech-Priests, who demand more of the Knights than their vows of realty require.{{Fn|29}}

The serfs of Questor Mechanicus Houses will perform similar roles to those of their Adeptus Terra counterparts, acting as labourers, support, and [[Knight Household Guard|militia]]. They often live in vast heavily polluted urban [[hive]] sprawls and slave away in manufactorums for their ruling Noble masters.{{Fn|29}}
