The blade's original purpose was to be used by Alice Quinn to kill the Beast, but it was stolen by Julia Wicker, who used it as leverage to make a deal with the Beast to help her trap and kill Reynard the Fox.
The blade was first discovered in Martin Chatwin's book at the Library of the Neitherlands, which described the blade as being able to slay almost anything, and that it hadn't been recovered by Martin after having been made. It is later shown that Quentin and Julia, after having travelled back in time over 70 years, have the blade commissioned by a blacksmith that a young Martin takes them to.
When Julia, Marina and Martin finally confront Reynard with the knife, they are interrupted by Penny, who runs into Julia and Martin, and teleports them to Fillory, causing the knife to fall onto the floor. We then see Marina and Reynard both reach for the knife. When Julia returns to Marina's apartment, Marina is shown dead on the floor while Reynard and the blade were nowhere to be seen. It is currently unknown exactly what happened to the Leo Blade.
The blade can only be touched by master magicians. It's high concentration of magical power burns anyone who is not powerful enough to wield it.
- The creator the Leo Blade also made the Virgo Blade.
- The blade takes approximately 70 years to make, due to the special properties of the moonstones.
