Stargate Command sent an advance operative to Tarsun’s Wheel to make an initial investigation prior to sending an entire team. The operative discovered it to be a Dyson’s Sphere, with a stargate and DHD housed in a structure on a continent that SGC dubbed “Primus.” After an initial survey revealed a feudal-type humanoid race (the Kamari) and an industrial-age reptilian race (the Miyori), General Hammond assigned SG7 to make official first contact. Ordered to learn what they could without alarming the locals, SG7 arrived at Tarsun’s Wheel only to discover another explorer already there. This explorer, Kentis, greeted them civilly but declined to share his background or reason for being on Tarsun’s Wheel. (Gar’i and Devero did piece together that Kentis was a Tollan, a race known for their advanced technology and great reluctance to share technological advances with other civilizations.)
Though he would not tell them the reasons for his being there, Kentis did explain that he’d heard some troubling rumors about problems on the Miyori border. He planned to investigate the matter and invited SG7 to accompany him. They travelled through two Kamari villages (one agricultural, the other a fishing village near a river), and Kentis convinced a village elder in the second village to let the entire team stay in his house for the night. SG7 tried to learn more about Kamarian culture from the village elder, but the old man was evasive. Devero took it upon himself to recruit Sam to help him drug and study their host in the middle of the night. Discovered by Kentis in the middle of this misadventure, Devero was completely unapologetic (though he had learned, at least, that the villagers were ordinary humans).
The following day, the team reached Miyori territory and were invited by an official to travel via automobile to their distant shoreline where an unknown watercraft had been sighted. Gar’i offered to drive the primitive vehicle and during the journey Kentis admitted that he had been sent by his people to investigate a fugitive believed to be somewhere on Tarsun’s Wheel. Upon reached the shoreline, however, the team spotted a distant, inflatable raft with half a dozen passengers. Interestingly, the raft had a swastika on the side. Kentis said that, whoever these people were, none were the fugitive he sought. The team went out in a boat to speak with the “space Nazis” – as the Miyori were apprehensive about approaching these strangers.
In a triumph of diplomacy, SG7 befriended the Nazis and learned from them that Tarsun’s Wheel had a second stargate (but this one lacked a DHD). The travelers were descendants from armies sent by Hitler to a planet they later dubbed “Himmel.” During WWII, Germany had possession of Earth’s stargate and learned to use it. By accident they succeeded in dialing up a distant planet, but didn’t realize that the gate could provide access to countless other worlds as well. Believing it was a single-address portal, they sent troops in search of better weapons only to discover a Goa’uld on “Himmel.” While the German forces eventually triumphed over the Goa’uld, they were under strict orders to not reopen the gate until they heard from the Fuhrer. They never did, and only generations later did they try dialing a different address. Tarsun’s Wheel was their first foray away from home, and this particular team had been stranded for months.
SG7 escorted the Himmelites to the stargate on Primus, and went through themselves to make a report on their progress so far. Before leaving, Gar’i learned from Kentis that the Tollan was searching for a rogue Goa’uld on the Wheel, and also that he had told the Kamari not to tell anyone about their ancestry, in case others (specifically, Goa’uld) came through the gate in the meantime. Kentis agreed to wait at the ‘gate house’ on Primus until SG7’s return.
