Cimmeria

Cimmeria is a planet under the protection of the Protected Planets Treaty, with the dominant race being the Cimmerians. The residents of this world are descendants of northern Europe, and firmly believe that the Asgard are gods that are protecting them. The planet is guarded by a device called Thor's Hammer. The weapon is capable of detecting symbiotes, and especially those of the Goa'uld. (SG1: "Thor's Hammer")

On this planet there is also the Hall of Thor's Wisdom which is a cavern where the Cimmerians are tested for the determination on their level of advancement as a society in a whole in general and as individuals in particular. (SG1:"Thor's Chariot")
