The Keybearers were ten elite Luminoth warriors who had organized to find and use the ten Ing Sky Temple Keys to infiltrate the Sky Temple. They were divided into two Cadres of five warriors each. Each warrior managed to find a key; however, all were subsequently hunted down and killed by the Ing before they could return it to the Temple. The sole exception was A-Kul, who left only nine Keys for Samus Aran to find. A-Kul left hints at the Sky Temple Gateway, where she succumbed to her injuries, as to the locations of the other Keybearers and the keys they tried to acquire.
The rooms where the Keybearers' bodies are found indicate the areas they were each assigned to explore. Two soldiers from Cadre 1 are found in the Torvus Bog, and the other two in the Dark Agon Wastes. Three bodies from Cadre 2 are found in the Temple Grounds and two in the Sanctuary Fortress, while the fifth member of Cadre 1, A-Kul, made it to the Sky Temple Gateway and died there.
Parallels can be drawn between the Luminoth Cadres and two Forces of GFMC Task Force Herakles, who were also all wiped out by the Ing. Eventually, Samus would enter the Sky Temple and destroy the Emperor Ing and Dark Aether, avenging both the Keybearers and Herakles.
