There are a bunch of Chaos-worshipping xenos in the Gaunt's Ghosts novel Traitor General . I think it's weird that Games Workshop has never developed 'Chaos Xenos' as a troop type in the tabletop game…

If anything, they'd be Chaos Cultists as per Codex: Chaos Space Marines. Though it does strike me as odd how humanity is the only prominent Chaos worshipping race in the setting. Every other race seems to have a resistance/immunity to it.

Kroot sound like they'd make great Khorne cultists, though, and there are Chaos Orks, mostly in the form of Khornate Stormboyz, though this is considered un-Orky by most Orks. It's usually viewed with a mixture of disappointment and exasperation, akin to a teenage 'Wiccan' phase in rebellion against their religious parents. Those that don't grow out of it get krumped.

Basically any race can be playable in Black Crusade thematically speaking. Every intelligent race is vulnerable to chaos, with 2 notable exceptions of Orks & Tau.

And even then it could just be they're affected differently. Farsight is very different in outlook to other Tau for example.

The only races that could not be played, I reckon, would be the Tyranids & Daemons. They're just too different. Tyranids sneak; eat; & evolve. Some higher order/independent types, Hive Tyrants/Warrior primes etc, may have a 'personallity'.

Daemons; are basic concepts, who are created a certain way, with basically no free will. That is why mortals/Daemon -princes are so prized.

And basically Daemons are fully corrupted & achieved apotheosis/spawndom already. Where do you go from there?
