Supreme power in the House is overseen by the various [[Archeoteks]], masters of tech-lore who oversee the secret STC at their core. While similar to the [[tech-priest]]s of the [[Adeptus Mechanicus]], these figures have no interest in the religion of the [[Omnissiah]].{{Fn|7d}} Beneath the Archeoteks are [[Primes]], who act as middle-rank overseers.
