Word Bearers: Which units fit the background?

[Lord_Caerolion]

The other thing to remember is that, barring Abaddon, you can't exactly say "no" to the Chaos Gods. If you've done enough bloodshed in the name of Khorne (while also offering praise to the others at the appropriate times) that Khorne wants to give you his Mark, what are you going to say? Because Khorne only hears the options "I accept your brand so that I may slaughter more souls in your name" and the less common "Khorne, please send your hound Kharanak so that he may rend the flesh from my ungrateful bones".
