"I didn't think that humans drank the blood of other humans," said Jun Li slowly, and I looked up at the lens in the corner of the bridge.
"There is no specific rule against it. There are some cultures that consumed the blood and flesh of their enemies, thinking that it would give them their power and strength in return. There are religions where, during every service, they are drinking the body and blood of their savior. Mind you, that is bread and wine, but the words still imply the true meaning. Then there are foods made out of the blood of different mammals. We, as humans, can eat the flesh of pretty much anything but another human at this point in time and not flinch."
I could draw on numerous historical and modern situations in which humans consumed the blood or flesh of something. And I was pretty sure that Tyris was more a rat than a human. Not like it would matter to most.
