You know, what would it taste like and how do you milk a vrock? They're avian, not mammilian. But as a chaos demon I suppose it could have whatever kind of anatomy it wanted.
I imagine it would be a deep orange, almost red. Each wheel probably has some vines growing out of it due to spore contamination. That might be part of the preservative rind, however.
Vrock milkers must be really tough. Retired Cincinatus tough, I mean.
Imagine a whole aviary of vrocks, and farmer Cincinatus coming in for the morning milking. The help are too terrified to help after what happened to poor Jimmy last week. But those vrock fly down obediently and get milked by Cincinatus because they don't wanted to get smacked with the holy stick, now do they?
OK, I'm going to bed now.
