1) This topic is was in the wrong place.
2) Why bother using a GW official planet? Write your own, and then you haven't got to worry about keeping to "official information"...
Cheers for migrating it for me.
As for wanting to use this planet, it is for a themed witch hunters force for 40K. I plan on sculpting 28mm scale Tyrus, Sgt Stone, Malicant, Barbaretta and a cyber mastiff as my =I= lord and retinue, and field them with inquisitorial stormtroopers and inducted IG.
Seeing as Barbaretta is described as being part of Tyrus' warband during his mission on Karis Cephalon, I thought it would be nice to model the guardsmen according to any existing canon for this planet.
I'm a bit of a fan of building armies around an existing theme- I've just finished a tournament force for the Chosen of Abaddon, and have an eldar army in the works themed around Arhra the fallen phoenix. I guess I just have a love for the stories and history of the 41st millennium.
Don't fear for my lack of creativity though- I have created two of my own worlds for dark heresy campaigns (a hive world that housed a genestealer cult, and a backwater planet with a real 'space western' feel to it), and am working on a tau army of human allies known as the Eastern Fringers (corporate [water caste style] driven military with Armored Core inspired crisis suits).
Oh my I went off on a banter there didn't I?

Back on topic, thankyou very much Kaled for finding that information for me! I assume there are no illustrations of their uniform then? I guess that leaves me with plenty of freedom for modeling. I shall certainly take up your advice on religious icons and the like; what good is a witch hunters force without tabards and relics and FIRE!
