"What was the widely believed lie behind the origin of the Faunus in the second age?"

“I think I know this... Uh- They thought that Faunus were half-human half-Grimm.”

“Correct, Ruby. I’m impressed. It was a common misconception that Faunus were a result of Grimm fornicating with distressed human women. This lie continued as a form of anti-Faunus rhetoric for the majority of the second age.”

“Honestly, such disgusting beliefs,” Blake grimaced.

“Was there even any evidence to prove that?” Yang added on.

Ruby, automatically, responded to Yang, “Maybe it happened once and people just assumed that’s how it worked.”

“Wow, Ruby. Right again:” Weiss congratulated, pointing to a paragraph in her history book, “‘this belief was first established when reports of a woman being forcibly penetrated by a Grimm (beowolf) had resulted in the birth of a wolf Faunus.’”

“So there is some truth to it,” Ruby uttered without thinking.

She immediately panicked that she may have said something a little ignorant or offensive, when she heard Blake speak up.

“Yeah, it does happen. Grimm making love with Humans can make a Faunus. However, the misconception is that it is the origin of Faunus. The Faunus existed well before the first recorded Grimm/Human relation. It’s an incredibly rare occurrence, anyway, since most Grimm would devour most Humans, rather than copulate. They’d only do that, if they were extremely... *cough* ... horny.”

“I didn’t even know Grimm could fuck. Let alone fuck Humans,” Yang said, crassly.

“Ew. Don’t say it like that, Yang,” Ruby cringed at the horrid use of the word ‘fuck.’

“C’mon, Yang. We had been so clean up until now,” Weiss agreed with Ruby.

“Yeah, sure,” Yang flippantly said, before smirking and asking, “So... what does get a Grimm *cough* extremely horny *cough,* just so I know to avoid it?”

Before Weiss could chastise Yang and before Blake could say that no body knows,

Ruby found herself answering...
