@ACWeapons Quote from the fic:

“What do we say of the Grimm’s origins?” He asked, falling naturally into his lecturing voice.

“They are creatures of darkness,” Jaune answered, by rote. They’d all heard the refrain many times before.

”And what does that actually mean?” Ozpin asked, eyebrow raised. Yang had never questioned it. She didn’t know anyone else who had either. “The truth is,” he continued, when he was met with silence, “that there are three conditions that must be met for the emergence of a Grimm.” Emergence. Not birth. Yang was starting to get flashes of infirmary quarantine and doctors in hazmat suits. Ozpin started numbering them off on his fingers.

“The first is the presence of dead flesh. Reasonably intact, though it doesn’t take more than couple of pounds. Human, faunus or animal will suffice.” Yang swallowed, the coffee sitting unpleasantly in her stomach. “Secondly, darkness. Grimm will not emerge into even dim sunlight. Lastly, an absence of Aura.” They all looked at him, confused. Death meant the dissipation of Aura, everyone knew that. Ozpin smiled sardonically at them.

“The process works like this. When a living being dies, its Aura fades away. This leaves a void. Darkness can fill up this void, twisting the flesh into a Grimm, but only if there is no nearby source of Aura. Often, passing scavengers pick the flesh clean before the transformation can occur, or their Aura is enough to halt the corruption. The whole process can take anywhere from hours to weeks.”
