Thor's Hammer

Thor's Hammer is said by legend to be a great weapon, wielded by the god Thor. The Hammer is also the symbol for the planet Cimmeria, a world forbidden to the Goa'uld. Thor's Hammer is the device which protects the people of Cimmeria from Goa'uld interference.

The device has several parts: Every person that comes through the stargate on Cimmeria is scanned by an obelisk with the Hammer symbol upon it. Those who are found to have a Goa'uld symbiote or larvae are transported to a networks of caves, and there confronted by a hologram of Thor. This hologram informs the prisoners that the only way out is to face the Hammer and have the Goa'uld parasite destroyed, only the host body can survive. The network of caves have the ability to negate Goa'uld weapons, once inside these devices will not function, but if the device passes through the Hammer it will work outside.
