"Battle brother Griff, what in the emperor's name is a Puma?"
"It's a kind of large cat, Brother-Sergeant."
"Do not make up animals, Battle-Brother. Do you see, how the bolsters at the front look like tusks? What sort of animal has tusks?"
"A... Walrus, battle-sergeant?"
"Did I not just tell you to stop making up animals?!?"
Okay, I like it now. I also want to make a Death watch team that's just the RvB cast.
