It was said that long ago, a bolt of lightning struck a dead tree on the ground. It caught fire and quickly grew into a raging wildfire. The animals living in the forests and grasslands had no choice but to flee for their lives. Those that failed to outrun the flames were burned to charcoal or roasted alive.

Cooking had a natural connection to chemistry, and the chemistry involved in cooking was also extremely complex. When meat was roasted, it was not like the Vinegar-to-Wine Charm, where covalent bonds changed. Instead, the intermolecular forces of non-covalent bonds changed, forming new molecular structures and altering the state of the meat.
Werewolves preferred raw meat, but that could not be generalized. Remus had no problem eating human food when he had not transformed, yet after transforming, he would attack even Harry and Hermione.
Defense Against the Dark Arts only taught students how to identify werewolves; it did not teach them how to kill them. Snape had nothing but contempt for the school's education.

For example, they used the new antlers that grew after old ones had fallen off. At that time, the velvet antlers were furry on the outside and full of blood within, known as
