But then when you read Apocalypse... It CAN occur. Hell in Apoc even nids can ally with anyone. I don't have a problem with any allies, I think people take the allies rules far to strictly, even in the BRB GW state that you can still use Come the Apocalypse allies with your opponent's agreement, just come up with a suitable reason for the alliance. I think Traitor Knights is more than just a 'suitable' reason for it, it's downright narrative.
Astra Miliwotsit? You're in the Guard now son....
Funnily enough, notice that anything Imperial isn't actually sculpted onto the model.I just hope GW make a special updated Chaos Knight miniature (with Chaos Symbols on it), EBook Codex, or release something like Hell Knights, and other Fallen Slaanesh Knight Titans to allow heretics and anti-Imperial generals like myself to field something other than the expensive 888 point Super heavy tank with a Chaos warrior on the front, that is not worth the points it costs.
Red like roses, fills my dreams and brings me to the place where you rest...
