The Systems Alliance is the representative body of Earth and all human colonies in Citadel space. Backed by Earth's most powerful nations, the Alliance has become humanity's military, exploratory and economic spearhead. While the Alliance is relatively new to the galactic community, it has already made a name for itself, gaining humans an embassy on the Presidium. The Alliance is governed by a parliament based at Arcturus Station; the station also serves as the Alliance's capital.
