The Green Lanter is another DC Superhero who has been part of American culture for decades. There have been several different Grern Lantern characters, but perhaps the most popular was Hal Jordan.
Hal was given a ring of power by a dying alien. As a last dying act, the alien sought out a human who was "utterly honest and without fear." The quest led him to Hal. Once Hal accepted this ring, he was initiated into the Green Lanter Corps, a sort of interstellar police force, orver seen by the Guardians of the Galaxy. The purpose of the Green Lantern Corps is to protect the innocent from evil, and the ring is the source of power used to do so.
When Hal charges his ring, he makes the following oath: In brightest day, in blackest night, No evil shall escape my sight. Let those who worship evil's might, Beware my power, Green Lantern's light.
Hal controls the ring telekinetically, and it forms a field of green light. It can carry him in flight, or it can form into any object that is needed at the time. Operating the ring effectively requires the Green Lanter to maintain focus. The power of the ring is not effective on the color yellow.
The Green Lanter cache is a family friendly cache, in hide location and contents. The terrain is alittle more difficult than some of the others. There is of course, a little Green Lanter loot in the cache.
