The Citadel Council intervened and negotiated a peace. The resulting First Contact War was relatively short and bloodless, lasting only months and costing 623 human lives (with a slightly higher number of turian casualties). While individual governments remained unsure on what action should be taken, the Alliance took control and attacked the turians.
Only one of the human ships made it back to Shanxi colony, which was subsequently discovered by the turians and invaded. Activating a dormant mass relay without knowing where it led had been declared illegal by the Council, though the humans did not know this.
A scout fleet consisting of three frigates and two cargo vessels, trying to activate a mass relay, encountered a turian patrol fleet. But despite this success, the Systems Alliance was not considered a serious political body, as it was considered to lack the authority of individual nations.Įight years later, humanity made first contact with another alien species and everything changed.
Maintaining this expansion policy, the Alliance activated all the mass relays it could find to seek out new resources and possible colonies. The Alliance began a rapid campaign of expansion, establishing numerous colonies and constructing a large fleet, even though it had yet to encounter another species.
