The Terran Alliance is the human civilization in the Zuit'uji universe. The humans created hyper-drive based on the old stargate designs, given to them by the Arceans. In one of the biggest blunders in galactic history, those same human scientists that developed the miraculous technology spread hyper-drive [and other requisite technologies] to the other civilizations. This event has led to the general consensus of humanity being reckless and unthinking about their actions, but the humans have since created a reputation as methodical warriors and excellent diplomats. The Terran Alliance joined the Alliance of Nations.
