Knights of the Round Table
From SGCommand
The Knights of the Round Table were the retainers of King Arthur. When Merlin descended himself, he entrusted his secrets to Arthur and the Knights. They also searched for the Sangraal, after Morgan Le Fay stole it. Legend says they travelled to three distant lands: Castiana, Sahal, and Vagonbrei. However, it appears that they weren't just searching for the Sangraal, but Merlin as well. (SG1: "Avalon", "Camelot", "Morpheus", "The Pegasus Project", "The Quest")
