"The Great Key, also referred to as the Great Weapon or simply the sword, is one of several keys forged by aliens that possesses the ability to activate alien temples throughout the galaxy. When one of these temples is activated, the bearer of the key gains access to the temple's treasures and capabilities. Initially believed to be an energy sword during it's first appearance, Tucker finds the key in a hole under the windmill in Zanzibar while the Blood Gulch Crew tries to assassinate O'Malley. It is later revealed by Gary to be a relic of a long lost civilization and is further explained upon by Santa in Season 13. Although not constructed to be a sword, the key has been shown to act as an efficient combat weapon."@en . . . . "The Great Key was a part of the Cetagandan regalia, along with the Great Seal.
