*Cimmeria is a safe world, protected from the Goa'uld by Thor's Hammer, a device at the end of a long underground labyrinth that kills any Goa'uld, leaving only the host alive. When SG-1 arrives, a mysterious device detects the Goa'uld within Teal'c, and sends both Teal'c and O'Neill to the underground maze. There they must fight for survival against the Unas, a vicious creature who was the first Goa'uld host. Meanwhile, Kendra, a former Goa'uld host who survived her own journey through the Hammer, aids Jackson and Carter in finding a way to rescue O'Neill and Teal'c, and destroy the Hammer. *Source: Back of card
