Gungnir

Introduction
Gungnir (lit. Swaying One) is an ancient Void Century spear, discovered in an equally ancient, faraway ruin by Peabody Rune, a former pirate member of The Four Legged Pirates and current Archaeologist for The Jolly Pirates. Due to its age and origins, as implied by Rune's research into the weapon's history, not only is it an invaluable piece of history, but perhaps a highly threatening weapon in the eyes of the World Government as well, due to its supposed date of creation. Interestingly, it's implied that Rune was destined to find and wield Gungnir, as many other people have tried using it, only to be weighed down by the spear's immense weight; whereas Rune apparently can pick it up as easily as if it were any other spear.

Additionally, Gungnir seems to wield rather otherworldly powers, making it quite a prized weapon. Among its abilities, it seems to be capable of elemental attacks, and can home in towards Rune's location, no matter where she is, after being thrown by her, among other powers. Due to this and its mysterious origins, it is perhaps one of Rune's most prized possessions, as she is never seen without it.

Trivia

 * Gungnir is named after the mythical spear of the same name in Norse Mythology, commonly under the command of the Norse king of the gods, and a god of war and magic, Odin. This Gungnir's ability to fly back to Rune's possession is similiar to the mythical Gungnir's magical power to home in on targets, allowing it to never miss its aim, no matter what.
