Editing Warhammer 40,000/Xenos in 30k (section)

=== Other Imperial Armies ===
Organizationally, nothing like them existed at this time at the kind of scale that compared with the Legiones Astartes. Even so, something like them probably existed on a small scale, so here is what you would usually proxy them as:

==== Adepta Sororitas ====
Adepta Sororitas models, in the sense of being some kind of band of elite Emperor-worshipping space missionaries in power armor, can be represented by the Solar Auxilia list (''Horus Heresy Book Four: Conquest''). They wouldn't have access to Heresy exclusive weapons like Volkite weaponry, Raipers, nor would they have Leman Russ, Malcador, or Baneblade variants. Arco-flagellants make decent stand-ins for Ogryn Charonites and Celestians make good stand-ins for Veletarii. While Penitent Engines could fill in for the Castellax, this would require having a Enginseer with a Cortex Controller to avoid becoming [[That Guy]]. Better yet, you could use Talons of the Emperor (''Horus HEresy Book Seven: Inferno'') and use the models to represent the Sisters of Silence.

==== Grey Knights/Legion of the Damned ====
Grey Knights and Legion of the Damned, as elite super-powered Space Marines without an acknowledged Legion tie, can be represented by the Blackshields list (''Horus Heresy Book Six: Retribution''), possibly led by one of the [[Knights-Errant]].

==== Imperial Knights ====
Imperial Knights can be represented by the Questoris Knights list (''Horus Heresy Book Four: Conquest'').

==== Cult Mechanicus ====
Cult Mechanicus can be represented by the Mechanicum list(s) (''Horus Heresy Mechanicum Taghmata Army List “red book”'').

==== Militarum Tempestus ====
Militarum Tempestus can use the Solar Auxilia list (''Horus Heresy Book Four Conquest'').

Don't do that - Do Militia with Survivors of a Dark Age, it's cheaper, and closer to what you want.

==== Inquisition ====
Inquisitor warbands can be represented with the Shattered Legions list (''Horus Heresy Book Six Retribution''), or the Solar Auxilia (''Horus Heresy Book Four Conquest'') or Imperialis Militia & Cults list (''Horus Heresy Book Five Tempest'') depending on exactly what you want it to look like.
