Genii

Humans from a planet in the Pegasus Galaxy. To outsiders, they appear to be simple farmers, resembling the Amish of Earth. In truth, the Genii actually possess a technological level roughly equivalent to that of Earth in the 1930s: they have electricity, primitive monochrome television viewscreens, and mass-produced firearms. Generations ago, survivors of a Wraith culling took refuge underground in bunkers left over from forgotten wars, and there rebuilt their civilization, expanding outwards into a massive series of secret underground facilities. Most importantly, the Genii have centered their efforts to fight the Wraith on a program to develop a fission bomb, to be delivered to Hive Ships. However, the Genii had not yet discovered how to make an effective trigger mechanism that would create an implosion, or an effective means of uranium enrichment, when the Atlantis Expedition encountered them. The Genii were angered that the Atlantis team had woken the Wraith from their hibernation early, but agreed to help each other. A resulting joint Genii-Atlantis mission backfired, resulting in the death of a prominent Genii leader and the failure of the Genii's attempts to plant a fission-bomb in Wraith Hive-ships (although the Atlantis team feels that there are so many--over 60--that the Genii's plan would only have destroyed a few). The Genii now count themselves enemies of the Atlantis expeditionary team, and are determined to obtain C4 explosives from the Atlantis team in order to build an effective trigger mechanism.
