The Great Library Fire of 2500 BCE
In ancient Babylon, a time-traveler's careless use of a fire spell caused the destruction of the Great Library of Alexandria. The resulting blaze raged for weeks, consuming not only the library but also the surrounding city.
A nearby witness described the scene: "I was having a snack when I saw the sky turn bright orange. Next thing, the entire city was ablaze."
