Tenninites

There is, within the psychological foundation of every forge
world, a deep-seated fear of Abominable Intelligences. Tales
from millennia gone by, of ages now more impossible legend
than story, speak of the near-extinction of the human race at
the hands of legions of faceless iron golems, crafted sentiences
that dared not only to think, but to think they were equal
to Man. The Omnissiah and the Fabricator-General have
forbidden the study of such fields, and any adepts who delve
into this illicit branch of research are branded as Khamrian
hereteks and hounded from the society of the Mechanicum, if
not immediately rendered to Servitude. There are those adepts,
however, who skirt the proscribed disciplines, seeking to better
understand the hallowed machine-spirits that serve Mankind
without, hopefully, falling into tech-heresy. The Tenninites
are one such a group that exists in Calixis, though there are
undoubtedly others even more furtive in their research.
Working primarily in small stations scattered throughout
the Lathe Worlds, the Tenninites focus primarily on ancient
machine-spirits, coaxing them back to active service and
seeking ways to enhance their awareness and performance. They
have achieved several minor breakthroughs that some might
consider tech-heresy, but few outside adepts dare utilize these
implementations given their source. Many assume there are also
major discoveries that the Tenninites dare not reveal, lest they
face the full wrath of the Lords Dragon. The sect assumes they
are under constant surveillance, and likely infiltration as well,
but so far has not faced outright action against them. This is
surely an indication of their skills in keeping their other results
all carefully hidden, until the proper time of revelation.
