Book: Special Weapons.
"Queenbreaker" was the label given to the Fallen who first rose to betray the Queen. Their coordinated attempt on Her Grace's life was quick and violent. Most of the Queenbreakers were eliminated, their line rifles taken as trophies. Some remain at-large.
Known as Queenbreakers' Bows, the very weapons once used in an effort to assassinate the Queen of the Reef are now prized possessions for Guardians—not only for their storied history, but for the chance to get their hands on fully functional Fallen weaponry.
