RFI: Chaos Knight Houses

[Xenith]

So my eye is gradually turning to Adeptus Titanicus, but more with a 40k setting. The Titans and knights will be tied in with my Thousand Sons/Iron Warriors, but the daemon/hell/renegade knights and titans will be Tzeentch aligned.
 
With that I have a request for information on some Tzeentch knight houses.
 
What I've been able to piece together is that we have 2 Tzeentch aligned houses:
 
House Arcanus and House Chromatic, and the titan legion Legio Proditor.

 

Does anyone have any ideas of colour schemes or additional information about these households?

 Stuff I wrote before I found this page.

Both are active in the Stygius sector in the 13th Black crusade, however it's uncertain whether they were already traitors, or if they sided with the Abaddon in M41.
 
Looking closer at the Stygius sector, the Prismata system seems a likely home for the House Chromatic, with a mining world, factorum world, and Chroma, a deathworld, which is likely where the house took it's name (knights being needed to defend against beasts, etc.
 
There is also an archive world which would be of interest to the servants of Tzeentch.

 

Any input is welcome!

Side note, I'll update the Tabula Questoris and Titan Legions indices to also include lists of houses/legions that have turned/fallen to Chaos.

Thanks for the move, wasn't sure the best place for the thread.
